Buyer Guide: How to Select the Best Washable Air Filter

blue washable furnace filters cleanedYou need to change the air filter in your HVAC every one to three months, depending on the quality of the air in your neighborhood

Before choosing the best cleanable furnace filters replacement, consider these tips:

Read the guidelines from the manufacturer

First of all, you need to look through the guidelines for your HVAC system. The manufacturer is sure to indicate what type of filter you’d better opt for that will fit your HVAC. The most important thing is the size. You will not be able to adjust the item that does not correspond to the indicated parameters. Buy the filter that precisely meets all the measurements to get the proper fit and let it be as efficient as possible.

Be sure to look at the MERV Rating

This includes the description of the qualities and characteristics. You need to know how effective the filter is at removing different particles and what kind of particles it can remove. The higher the rating is, the more harmful substances the filter can block. For example, if you see that the filter rating is between 1 and 4, which means it can stop about 60 to 80 percent of those airborne particles. If the MERV rating is 5 to 8, the efficiency increases to 80-95 percent. The air filters rated 9-12 can block about 90-98 percent of those pollutants.

There is an essential point to consider here. If a filter demonstrates a higher ability to block particles from the air, that decreases the efficiency of your HVAC. That’s because more effective filters are finer and the air conditioner has to use more energy for pulling the air through it. So, it’s always essential to find the necessary balance between the effectiveness of the filter and conditioner. The most appropriate rating recommended by homeowners is 7-8.

Choose between disposable and washable filters

Disposable filters seem to be more convenient in a short-term perspective because you can throw them away after using and replace them with new ones. However, a washable air filter, though more expensive, can last for years, so saving costs is obvious in the long-term perspective.


Are washable furnace filters any good?

Sometimes, they say that only disposable air filters work well trapping the smallest particles, and washable filters can trap only large particles and dust. However, there are washable filters that can trap pet dander, smoke, and bacteria as well. Read the instructions carefully to make the right choice.

Are washable furnace filters expensive?

Washable air filters are not so expensive. You can get them on Amazon for about $30-$100. There may be other extra expenses for shipping. However, some filters can be shipped for free.

How do washable electrostatic filters work?

The best electrostatic air filters rely on multiple filtration media layers. They can clean the air while it goes through them. The particles of dust and debris are captured here with the help of friction between the air and the air filter media made of the woven polypropylene with electrostatic properties. The air filter removes all the airborne particles before your HVAC system conditions the air. It protects the mechanical components of the HVAC and cleans the air inside your house off the dust.

What kinds of washable filters are the best ones?

Among a variety of furnace air filters that can be seen on the market these days, the best ones are those that are easily installed and removed, then washed and reinstalled without wasting much time and effort. Such filters should be washed easily in the shower tub or kitchen sink. Maintaining them should not require any special skills and the effects can be felt immediately after the installation.

How do I clean a washable furnace filter?

Reusable or washable air filters should be checked for dirt just once a month. If you notice some clogs and debris, you will have to clean the filter using very simple steps in the following order:

  • switch off the furnace or conditioner;
  • find the service panel and unscrew the cover using a screwdriver or other tools at hand;
  • locate the filter: most often, it can be found next to the blower;
  • rinse the filter you have just removed with clean water using your kitchen sink or garden hose outside;
  • set the filter to dry;
  • replace the item, the service panel, and the cover to turn on your appliance again.

Wrap Up

Remember that using effective washable furnace filters is much more efficient than disposable ones. Such filters will save your money, effort, and time in the long-term perspective. 

You will always be sure that you can clean your filter and get the quality air again without any rush to buy a new filter for replacement. That will spare you from getting worried all the time, and your air will always be clean.
