Why don’t washable air filters measure up to pleated?
Washable filters kind of live off in their own world when it comes to air filters. They work so differently than a pleated or even fiberglass filter that the MERV rating isn't particularly applicable to them, thereby making their efficiency harder to understand.
How are pleated filters charged?
As mentioned above, pleated filters fall into two categories when discussing electrostatic air filters. Some are charged with a charging procedure while they're being built. This is done with a process involving a bunch of tiny needles, but we won't get into that because it will probably bore you out of your skull.
Why do washable filters blow out?
Washable filters, because of their multiple layer construction, also have an extremely high initial pressure drop. If you're unfamiliar with that term, it basically means that airflow through the filter is initially lower than other types of filters. If airflow dips too low, your HVAC unit can struggle to pull in enough air and have to work harder. This costs you more on your heating and cooling bill and may potentially blow out the motor. Pleated filters don't really have this problem unless you leave them in the vent for way too long.
Why are pleated filters more effective?
Pleated filters also become more effective as they age because of the buildup of particles, which actually helps block more particles. The opposite is again true with purely electrostatic washable filters. Once dust and pollutants have coated the entire filter, the static electricity is weakened significantly.
What is Electrostatic Filter?

How does an electrostatic filter work?
An electrostatic filter uses a special sandwich of material layers that creates a charge of static electricity when the air flows over and through them. This static electricity attracts airborne particles like a magnet, causing them to stick to the filter media while cleaner air flows into the system. When the filter becomes dirty, you rinse it out, allow it to dry, and put it back in place.
Why do air filters look dark?
A traditional air filter has a straightforward method of action: it uses a microscopic mesh to trap the particles floating through the air. These particles could be dust, mites, pet dander, and other allergens that can impact air quality. Over time, this mesh fills up with the debris it traps, which is why filters often look very dark when you remove them during a monthly change. Most regular filters are only good for a single use before replacement.
Do you have to wash electrostatic filters before changing them?
