Unlike the disposable filters that are polluting our environment, these washable filters will aid you and your future at the same time. So, wondering where you can find reliable products? Check out our list below for a comprehensive review of the washable air filters.

How To Pick The Best Washable Air Filter?

How To Pick The Best Washable Air Filter?

Washable air filters seem pretty easy to pick but the actual scenario is completely different. You'll be offered products that are way off from their value proposition and aren't as good. This is why you need to look for following features in an air filter:


Size always matters regardless of the object type and purpose. It matters for washable air filters as well. Hence, you need to check whether the filter fits in your system before purchasing. Undersized air filters will rattle and sometimes fall off from your surface.

Usually, most filters are 16″x20″x1″ in size; check your system before purchasing the common sized filter.

Decent MERV Rating

MERV or the minimum efficiency reporting value rating indicates how well a filter performs filtration. For your HVAC system, you need an air filter that has just the right level of MERV. High MERV usually means that the furnace will trap all particles, but will also decrease airflow.

On the other hand, low MERV ensures great airflow but doesn't keep the air clean. So go for a filter with MERV of 7-13.

Good Quality Frame

Most users purchase a washable air filter because they'd like to use it for a long time. That is why the filter needs to be made of good quality materials and has to have a sturdy frame.

You certainly have come across many filters made of paper frames. These filters will break and warp easily under pressure. Hence, go for products made of metal or aluminum for long-term usage.

Pleated Surface

Folds on the surface of a filter gives it more surface area. A smooth air filter won't be able to catch as many particles as a pleated air filter. So, stretching out a pleated surface will result in more space, which is what we're trying to accomplish here.

Mesh Or Metal Screen

Looking for an air filter that'll last longer than any other machines in your home? Purchase one that comes with a metal or mesh screen. This screen protects the filter from high airflow of the HVAC system. Likewise, it will ensure that the filter doesn't bend or damage under force as well.

Easy To Clean

As these filters aren't disposed of as often, you will need to clean them thoroughly. Most filters can be cleaned using plain water or mild detergent. Go for filters that don't require extra maintenance after cleaning.
