⭐ Reviews – Best Microplastics Filters [Year]

Key Features:

  • Reduces microplastics in whole home water – The Evo E-1000 uses a catalytic carbon block filter with 0.5-micron pores. The average size of microplastics is 2.5 microns, so this Evo filter has small enough pores to thoroughly remove tiny plastic particles from your water.
  • Also removes or reduces 100+ other contaminants – According to the manufacturer’s contaminant removal data sheet, some of the other contaminants removed by this filter are chlorine, chloramine, VOCs, lead and other heavy metals, chloroform, and pesticides.
  • 15 GPM flow rate – This system shouldn’t reduce your water flow or pressure even during times of peak use, with a rated 15 GPM service flow rate that’s higher than most people will need.

Best For:

Anyone who wants to spend their money on the best-value, most capable solution to remove microplastics from their whole home water supply.


  • The Evo E-1000 Whole House Water Filter is much more capable of removing a broad range of contaminants (including microplastics) than a standard carbon filter. How? Because the system uses catalytic carbon block media, an upgraded version of activated carbon that allows for more thorough contaminant removal.
  • We appreciate that this Evo filtration system is designed for POE installation. It’s the only filter on this list to protect you from all possible sources of microplastics exposure through your water, including in water vapor from your shower and through dermal exposure from bathing or washing in water containing microplastics.
  • Installing the system is pretty easy for a whole-home unit – it has a simple design with just two filters and two connections. Maintenance is easy, too, since the sediment filter has a washable, reusable design and the carbon filter lasts for 1 year.


  • We’d love to see a percentage removal figure for microplastics on the data sheet. We had to obtain this information from speaking directly to the manufacturer.
  • The filter isn’t officially NSF certified for its performance, which would make it an even stronger contender in our eyes.

🤔 What are Microplastics?

Microplastics are tiny plastic particles that are formed when plastic products gradually decompose and break down in the environment.

There are numerous plastic products that may decompose to form microplastics, including plastic bottles, plastic bags, straws, and synthetic clothing. When these products are disposed of and end up in landfill and oceans, they cause microplastics to infiltrate our soils, waters, and atmosphere.

Because microplastics are so abundantly found in the atmosphere, it’s impossible to avoid exposure to them. We’re exposed to microplastics in the air we breathe, the clothes we wear – and the water we drink.

🚰 Do I Need a Water Filter That Removes Microplastics?

It’s estimated that Americans are exposed to between 39,000 and 52,000 microplastic particles in their food and water every year – and that’s enough evidence for us to say that yes, you need a water filter that removes microplastics.

As we mentioned above, plastic pollution is such a widespread problem that it’s impossible to avoid. Regardless of where you live in the country, and whether you’re in a rural region or in the heart of the city, you’re equally likely to be drinking microplastics in your tap water.

You can’t escape microplastics by drinking bottled water, either, since bottled water is sourced from springs and even tap water supplies that are likely contaminated with plastic particles. The only exception is bottled water that has been purified with a process that removes microplastics.

Even trace amounts of microplastics are thought to pose a danger to human health, but the EPA hasn’t established a legal limit for these contaminants in drinking water, so water utilities aren’t obliged to reduce microplastics to within a specific concentration.

What does that mean? Your water supply could contain very high levels of microplastics, and your utility doesn’t legally have to do anything about it.

🚱 How Do Microplastics Get Into Drinking Water?

There are a few different ways that microplastics can get into the freshwater supplies that are used for drinking:

  • From surface run-off
  • In wastewater effluent
  • Pollution from industrial effluent
  • From atmospheric deposition
  • From contact with degraded plastic waste

Landfill leachate and soil migration can also cause plastic particles to contaminate groundwater (underground) water supplies.

🩺 Why are Microplastics Dangerous to Our Health?

Some of the potential effects of microplastic pollution are:

  • Weakened immune system
  • Reproductive damage (caused by exposure to the phthalates used to make plastics more durable)
  • Developmental issues in children
  • Hormone disruption
  • Inflammatory diseases
  • Organ damage
  • Cancer

We might now be trying to reduce our plastic consumption, but microplastics from bottled water and tap water worldwide have already done their damage. Research conducted in early 2022 discovered microplastic pollution in 80% of human blood, where these particles could easily travel around the body and cause cell damage in various organs.

🧪 How to Test for Microplastics in Water

The best way to test for microplastics in your water is to conduct a laboratory test.

You can buy laboratory water tests for microplastics that cost $100-$500, depending on the complexity of the test.

Testing involves taking a sample of your tap water or bottled water, then sending it to the laboratory for analysis.

The lab will return your results within 7-10 days, and you can decide from there whether or not you want to remove microplastics from your water with a dedicated filter.

🧾 Microplastics Water Filter Buyer’s Guide: How To Choose Between The Best Water Filters For Removing Microplastics

Here are some of the most important factors to consider when deciding on which water filter for microplastics removal is best for you.

Your Budget

First, consider your budget, both for an upfront purchase and for ongoing maintenance. This will determine the types of filters that you have the choice between for microplastics removal.

If your budget is small, your options will be limited somewhat, but you can still find a highly capable water filter for removing microplastics.

In this case, we recommend water filter pitchers, which cost less than $100 upfront. Some of the best pitchers – like the Clearly Filtered Pitcher reviewed in this guide – are just as capable as the bigger, more complex filtration systems, reducing up to 99.9% microplastics.

If you can afford to spend hundreds of dollars upfront on a microplastics filter, you can have your pick of all the different filter types and configurations available. You might even consider a premium pick, like one of the reverse osmosis systems we’ve mentioned in this guide.

Filter Materials & Filtration Method

Microplastics are typically around 2.5 microns in size, but smaller plastic particles as tiny as 0.7 microns have been detected. That means that standard carbon block filters, powdered activated carbon filters, or any other carbon filter types aren’t typically capable of removing all microplastis because their pores aren’t small enough to trap these contaminants.*

*Check a carbon filter’s pore size to be certain. Some filters have pores as small as 0.5 microns, making them capable of removing microplastics, while others have pores as large as 50 microns, which will make them no good for microplastics removal.

With that in mind, some of the filtration methods that do work for microplastics removal are:

  • Reverse osmosis filters – with a pore size as small as 0.0001 microns
  • Microfilters and nanofilters – with a pore size of around 0.2 microns
  • Ultrafiltration membranes – with a pore size of 0.02 – 0.05 microns
  • Some ceramic filters – ceramic filters with a pore size of less than 2.5 microns can reduce microplastics
  • Some carbon block filters – with a pore size as small as 0.5 microns

The smaller the filter’s pore size, the more thoroughly it will be able to reduce microplastics because it will target even the smallest microplastic particles.

So, reverse osmosis filters are the best option for removing microplastics from water because they have the smallest pore size. They should also be capable of removing nano plastic particles as small as 0.001 microns.

How can you choose which filter type is best suited to you? We recommend also considering the other factors we’ve mentioned in this buyer’s guide, including your budget, your preferred filter use point, and your installation and maintenance preferences.

Different types of water filter cartridges

Filter Use Point

Also consider where in your home you would prefer to install and use your filter.

There are a few different options here:

  • Point of use filters, including under-sink filters, countertop filters, and faucet filters
  • Point of entry filters, or whole-home water filters

Before you get down to specifics, your first job is to decide whether you prefer a point of use filter or a point of entry filter.

If you want to remove microplastics from all the water you use in your home, including the water you shower in, cook with, and wash your clothes with, you should look at point of entry filters.

Since microplastics are thought to be capable of being absorbed through the skin and can also be inhaled in the atmosphere, installing a point-of-entry filter will reduce your risk of dermal exposure of exposure through inhalation to this contaminant.

Or, your main focus might simply to be to remove plastic particles from your drinking water. In this case, you can install a point of use drinking water system that’s installed in a location that’s intended to treat your cold tap water only.

If you choose POU filters, you have a few more options to consider. There are countertop filters of various kinds and under-sink filters that are capable of removing microplastics, and their each have their own unique pros and cons when it comes to flow rate, contaminant removal, filter capacity, and more.

We’ve discussed these features in more detail later in this guide.

Microplastics Removal Capability

Next, you need to consider the important element of microplastics removal.

If a water filter is capable of reducing microplastics, the manufacturer should list the filter’s microplastics reduction percentage.

Different types of filters can remove different quantities of microplastics. As we mentioned earlier, this mostly comes down to the filter pore size. The smaller the pores, the smaller the plastic particles the filter can trap, and the more thoroughly the filter can remove microplastics.

If you want to protect your family from exposure to microplastics in your drinking water, we recommend finding a water filter that can remove at least 90% of microplastics.

The very best filters, like most reverse osmosis filters, remove microplastics with 99% effectiveness or more. That means your water will contain less than 1% of its original microplastics concentration after it has been filtered.

Getting filtered water from an RO system

Flow Rate

The flow rate of a water filter for microplastics removal depends on the filter type and use point.

If you don’t want your water filter to disrupt your normal access to drinking water, install an under-sink filtration system that will filter water before it reaches your faucet. Most under-sink systems deliver a flow rate of around 1-2 GPM, which is about normal for a kitchen faucet anyway. That means you can access a steady stream of filtered water whenever you turn on your tap.

If you don’t mind taking a few extra steps to enjoy filtered water but you still don’t want to wait around whenever you need a drink, consider a countertop reverse osmosis system. You’ll need to pre-load the unit with a batch of tap water in the morning, but the unit should dispense water near-instantly whenever you press the button. Again, the flow rate for this type of system is around 1-2 GPM.

You might also consider gravity countertop water filters and filtered water pitchers, which are the most affordable solution for removing plastic particles but have the slowest flow rates.

These filters rely on gravity to send water through the filter media, so rather than delivering filtered water instantly, they take a few minutes to provide enough water for drinking.

However, while gravity filters have a slower flow rate, it doesn’t feel like it if you plan ahead. Fill your pitcher or countertop filter with water in the morning, and you’ll soon have a batch of filtered water that you can pour or dispense throughout the day whenever you want it.


You already know to look for a water filter that can remove at least 90% of plastic particles from your tap water – but how can you be certain that the manufactuer’s claims are accurate?

We recommend checking for third-party test results or an official NSF certification for the filter’s performance.

Many of the best microplastics water filters have third-party testing by IAPMO or another trusted organization that proves their contaminant removal abilities. Testing is typically conducted in a laboratory and exposes the filter to a contaminated water source to determine its filtration or purification capabilities.

The manufacturer should share a test report online that lists all the contaminants that the filter can remove, and to what percentage. If microplastics are listed on the report, you know that the filter is capable of removing these from tap water supplies.

You can also look for filters with an official certification to an NSF Standard for microplastics reduction.

As of yet, there isn’t an official NSF certification for the reduction of microplastics. However, reverse osmosis systems can be certified to NSF 58 for reverse osmosis performance, including the ability to reduce the tested-for contaminants, like microplastics.

You can search for NSF drinking water systems here. Scroll down to the bottom of the page and check the ” Microplastics Reduction” checkbox, then click “search” to bring up the results.

Filter Capacity & Lifespan

Filter capacity and lifespan tells you how long a filter will last before it needs to be replaced – which, in turn, helps you to understand the value of the upfront purchase.

Water pitcher filters are the cheapest way to remove microplastics from water, but they also have the smallest filter capacity and the shortest lifespan. So, even though you pay less upfront for these filters, you pay more money, more often to replace the filters. The average filter lifespan in a water pitcher is 2 months.

Other point of use filters have longer lifespans. Gravity countertop filters have an average lifespan of 10-12 months, while under-sink systems have a 6-12-month lifespan.

Some systems, like RO units, have multiple filters with their own unique filter lifespans. RO membranes last as long as 2 years, while their carbon filters last around 6-9 months and their sediment filters last 6 months on average.

Installation & Maintenance

On a similar note, consider the installation and maintenance work that you’re happy to commit to for a water filter that can remove microplastics.

If you hate DIY or you want to avoid the hassle of any sort of major setup, consider a countertop gravity filter or RO unit, or a pitcher water filter. These systems require no installation whatsoever – you just assemble the unit and slot the filters in place, then they’re ready to use.

If you don’t mind putting a bit more effort into the install, you can also consider under-sink systems, which need to be connected up to your cold water line but offer the convenience of filtered water on tap.

As for maintenance, that depends on your chosen filter’s expected lifespan. The shorter the lifespan, the more frequently you’ll need to replace the filter.

On average, you can expect to replace the filter every 2-12 months, depending on the type of system you buy.

Aside from filter changes, you will also need to clean the system according to the user manual.

Installing the top reservoir of the Clearly Filtered pitcher

Customer Feedback

The manufacturer will only tell you what you want to hear, and you won’t have a true understanding of a filter’s usability, longevity, and quality without reading customer feedback.

Reviews tell you how a product has lived up to a customer’s expectations. While it’s normal for any product to receive a small percentage of negative feedback, we recommend looking for a filter that has at least 80% positive reviews from happy customers.

When reading customer reviews, pay attention to what reviewers have to say about the filter’s performance, ease of use, and durability. These are all important factors to consider when deciding whether or not a filter is worth the upfront cost.


Finally, don’t buy a filter for microplastics unless it has some form of warranty or guarantee.

Different filters have different purchase protection, depending on the upfront cost of the product.

Countertop and pitcher filters may have a lower guarantee of 30-60 days, while the more expensive RO systems might have a 60-day guarantee and a warranty of 1-3 years or more.

Avoid filters that have no sort of warranty of guarantee at all, since that means the manufacturer isn’t obliged to send you a free replacement part or product if you receive a faulty filter.

❔ Frequently Asked Questions

Which water filter removes microplastics?

A variety of water filters remove microplastics. If you want to know which water filter types remove these contaminants, there are under-sink filters, whole home filters, countertop filters, and portable filters that fit the bill. Some of the best filter products that remove microplastics are the Clearly Filtered Pitcher, the Evo E-1000 Whole House Water Filter, and the Waterdrop G3P800.

Do Brita filters remove microplastics?

No. While Brita filters might remove a few larger microplastics particles, you can’t rely on a Brita filter to remove all microplastics from your water, and Brita doesn’t advertise its filters as being capable of microplastics removal. If you’re looking for a water filter pitcher that can remove microplastics, we recommend the Clearly Filtered Pitcher.

Does ZeroWater remove microplastics?

Yes, ZeroWater filters up to 99.9% of microplastics from drinking water. We think this pitcher is a worthy contender, but it hasn’t made our list of the best microplastics filters because there are other water filter pitchers that are more capable in this respect.

What is the best water filter pitcher for microplastics?

In our opinion, the best water filter pitcher for microplastics is the Clearly Filtered Pitcher. This water pitcher removes more contaminants than any other pitcher we’ve reviewed, including up to 99.9% microplastics.

Why can’t we filter microplastics?

The reason why it’s a struggle to filter microplastics with a standard water filter is that microplastics are tiny enough to slip through the pores of these filters. It is possible to filter microplastics, though – you just need a specialized filtration method or a filter with small enough pores to trap microplastics.

How long does it take to filter microplastics out of water?

It takes a couple of minutes to just a couple of seconds to filter microplastics out of water, depending on the filtration method you use. Water filters connected to your water line, like whole home filters and under-sink filters, provide instant microplastics filtration. Countertop units like water filter pitchers and reverse osmosis systems take 2-15 minutes to filter microplastics on average.

How effective are microplastic filters?

Microplastics filters have the potential to be highly effective – but not all filters offer an equal performance. Some filters, like the Clearly Filtered Pitcher Evo E-1000 Whole House Water Filter, remove virtually all microplastics from water, as well as tens of other contaminants, so they’re our top recommended filters for this purpose.
