What Are Washable HVAC Filters?
Washable furnace filters are a special type of filter that can be cleaned periodically and reused.
These electrostatic furnace filters are almost all made from synthetic materials as compared to the typical disposable filter that is made from cotton blends.
Washable furnace filters usually last from 3-5 years with monthly cleaning, but some filters are rated for up to 10 years.

What Are The Benefits of Washable AC Filters?
The main benefit of washable filters is that they last a number of years, so you won't have to replace it monthly (and I find most people forget).
If you add up the cost of buying a disposable filter, it can be sizable. For a washable filter, it is only a one time cost.
Of course, the downside is that you have to clean and dry the filter every month --- but at least you won't have to drive to the Big Box store and buy a new one.
Washable filters also are much sturdier and rugged than the average disposable filters.
Disposable filters usually have a cheap paper frame (compared to metal) that will bend easily. Many times I have seen disposable filters that have warped and literally sucked into the duct system.

How To Pick The Best Washable HVAC Filter?
This may seem like an obvious point, but you want to buy the right filter size for your system. You can pull out the disposable filter and look at the dimensions. The most common filter size is 16" x 20" x 1".
One of the most common complaints when it comes to washable filters is a poor fitting filter. If the filter doesn't fit properly into the furnace such as being undersized, then it may rattle and make noise when the HVAC system is on.
Besides the sound annoyance, this will also allow air to flow around the filter defeating the entire purpose of buying a washable filter.
Of course, this problem also applies to disposable filters. I have been on many home inspections where the disposable filter was allow air to flow around the filter.
In addition to air flowing around the filter, you also want to make sure that the filter slot or opening is fully sealed. The most common way to seal the filter slot is with a metal cover or sleeve --- though removable tape can work in a pinch.
High MERV Rating
The main rating for furnace filters is the MERV rating (minimum efficiency reporting value) which basically means how well the furnace traps particles.
The higher the MERV rating means that the filter is better at trapping particles (but also lessens the HVAC air flow).
There have been numerous studies that say residential homes should aim for a filter with a MERV rating from 7-13. A filter in the 7-8 MERV range is considered average, while 9-11 is high.
Just remember, studies have shown that MERV ratings higher than 13 in general do not outperform the lower MERV ratings --- and may even damage your HVAC system by causing it to run harder.
Pleated filters is when there are ridges or folds within the filter which gives it an accordion-like look to it.
These folds give the filter more surface area. If you stretched out a pleated filter, it will be much longer than the actual size of the finished filter.
When a filter has more surface area, this means it will be better at catching particles. This is why in general pleated filters are better than non-pleated.
When someone buys a washable filter, they want it to last a long time --- maybe even years.
During my home inspections, coming across a warped or damaged filter is extremely common.
This is because the disposable filters have a paper frame, which can easily bend when the force of the HVAC air flow is applied against it (especially if it isn't installed tightly).
If the filter doesn't last, then all of the potential savings over a disposable filter is never realized.
Reusable filters with rugged metal frames are definitely preferred over cheap plastic framing.

The air flow of an HVAC system can produce a significant amount of force on a filter.
Another way to add rigidity to a washable filter is by including a metal or mesh screen that sandwiches the filter media.
If you buy a washable furnace filter with a metal screen, this will help prevent it from bending or warping over the years.
How To Clean A Washable Furnace Filter?
To clean a washable HVAC filter, simply follow the manufacturer recommendations. The most common way to clean a washable filter is to take it outside, and spray it with a garden hose. If a hose is not practical such as during winter, you can also simply wash it under a kitchen or utility sink.
If the filter is very dirty, it is a good idea to soak the filter in a bin with some mild dish detergent.
After cleaning, you always want the filter to air dry before reinstalling into the furnace.
With washable filters, it doesn't really matter what direction you install the filter, but some brands do include an arrow just so you can consistently install it the same way.
