  • Works as well as 50 cleaning wipes
  • Outperforms other filter methods
  • Partner of 3M
  • Traps various particles

This incredible product by Filtrete is our overall best choice for a furnace filter for dust. They come in a variety of sizes; from 14 L x 20 W x 1 H inches all the way up to 20 L x 25 W x 1 H inches. Each of these sheets holds the equivalent amount of dust as 50 traditional dusting wipes. The product even continually outperforms fiberglass, non-electrostatic, and washable air filters.

Filtrete makes these products with 3-in-1 technology from the brand 3M. This helps trap dust particles in the air while letting through clean air. The product traps particles like pet dander, smog, smoke, pollen, and lint with ease.

In addition, the product has a 1000D MPR rating. The higher the number on this scale, the greater quantity of micro-particles particles the sheet can capture. This number is incredibly high, and one of the many reasons we recommend this product.

To get the best use out of this product, you should change your air filter sheet at least once every 90 days. If you opt for the thicker sizes (up to four inches), then you’ll only need to change it once every year.

An electrostatic filter uses electricity to charge particles which will then stick to the filter, securing them in place. Over time, the filter will build up a layer of dirt and you’ll then need to remove this dirt.

This product saves you money over time, as you won’t have to continually buy new filters. Instead, just take the filter down every few months and give it a wash. This will dramatically improve the lifespan of your air filtration system.

Buying Guide

How to pick a furnace filter for dust

Furnace Setup

When picking an air filter for dust, there are two ratings and two considerations you should take into account.

These two ratings are the MERV rating and MPR rating, which we will discuss further in the buying guide.

In addition, you need to consider the size of the filter and if you want a reusable one.


Before buying a filter from this list, be sure to measure your HVAC unit. You can’t get a filter that’s too big for your unit, no matter how efficient it is. Make sure your HVAC and filter will fit together correctly.


A few of the products on this list are reusable. You’ll be able to take them down and wash them, so you can keep them forever. While they’ll experience some deterioration over time, they will still last for years. Because of this, they’re more expensive than the non-reusable items on this list.

Before purchasing a filter, think about which option will work best for you: spending more upfront for a reusable filter or getting a strong filter that you’ll need to change every so often.

If you’re unsure, think about the purpose of your filter. Do you want it because you have dust allergies? If so, we suggest choosing the stronger, non-reusable filters. However, if you’re just getting a filter to improve your air quality, then a reusable filter will be more than enough.

What features should a furnace filter have for dust?

The best furnace filters for dust have a combination of a high MERV rating and a high MPR rating. These two figures demonstrate the number and size of particles that a filter can capture. With both the ratings, the higher the number, the more efficient the filter will be at capturing particles.

Let’s take a look at these ratings in more detail.

MERV Rating

A MERV, or Minimum Efficiency Reporting Values, demonstrates a filter’s ability to capture small particles. It’s a scale of efficiency and it shows the average particle size in microns that a filter can catch.

A MERV rating of 1-4 will capture particles sized 3.0-10.0 microns 20% of the time.

A rating of 6 will capture particles sized 3.0-10.0 microns 50% of the time.

A rating of 8 will capture particles sized 3.0-10.0 microns 85% of the time.

A MERV rating of 10-16 captures smaller particles measuring 0.3-1.0 microns. Filters with this rating are incredibly efficient, capturing up to 90% or more of the smallest particles. Anything with a MERV rating over 10 is incredibly efficient.

MPR Rating

Micro-particle Performance Rating (MPR) demonstrates a filter’s ability to trap small particles. These particles are between 0.3 and 1 micron in size. Considering a human hair is around 70 microns, a product with a good MPR can trap things 70x smaller than a piece of hair.

The higher an MPR is, the smaller the particles it can trap. When looking for a furnace filter for dust, MPR isn’t the most important rating since dust is a large particle. However, if you’re looking to trap allergens or pollution in addition to dust, then a higher MPR can help.

Do furnace filters help with dust?

The dust filters on this list trap dust and prevent it from circulating. Filters with high MERV and MPR ratings will easily be able to trap dust, as well as other particles like allergens.

The filter strips will trap the dust, collect it and ensure it doesn’t spread throughout your home. Not only does this reduce dust, but it also improves the efficiency of your air filters over time. This will save you energy and cut down on your bills.

Overall, these filters are one of the best ways to prevent dust from accumulating in your home. They only take a few seconds to install and will make a big difference.
