What Are Washable Electrostatic Air Filters?

The main difference between Electrostatic HVAC filters and disposable air filters is that they are recyclable, washable, and reusable. With Electrostatic filters, the airs that undergo through the filter and pass through various filtration channel layers are typically woven Polypropylene, which has an Electrostatic charge.

Aerial pollutants then become charged as they pass through the filter substance. They function as a magnet; the elements remain consistent with the filter channel as the air moves through the filter layers. Lastly, the air’s output is purified air that is prepared to recirculate all over the house.

Washable furnace filters are a special kind of filter that can be washed sometimes and later on reused. These Electrostatic furnace air filters are made from artificial substances instead of the usual disposable filter comprised of cotton mixtures.

Washable furnace filters typically continue from 3-5 years with monthly cleaning and washing, but some filters are ranked for up to 10 years.

How to Care for Washable Hvac Water Filters?

Furnace filters invite dirt, mold, dust, and other impurities which develop inside the fibers. To ensure the best possible air quality when the heating or air conditioning is working, recyclable filters need to be washed frequently.

Following is the step by step process of caring for washable HVAC water filters:

  • Just use flowing water to wash away the remainder and dirt. This can be performed in a sink or tub or even the outer part using a garden pipe. A flexible nozzle or sprinkler can help fasten up the method and electricity away from threatening the accumulation.
  • Leave the filter to dry in a sunny, well-ventilated place. This step is necessary because the additional humidity can become a propagation area for the development of fungus, mold, and mildew.
  • Once the washable filter is washed and dry, it’s prepared to be put back into the HVAC system.

Pros of Washable HVAC Filters

Purchase & Replacement Costs

When considering the cost of HVAC filters, it’s advisable to look for the long-lasting expenditure. Washable furnace filters are more costly. The standard price for the best washable filter varies from $60 to $120.

Though the advance cost is higher, it’s essential to consider that washable filters are likely to continue for almost the same number of years as your unit. By measuring the investment cost throughout an HVAC system, homeowners can save money in the long run.

Environmental Impact

Environmental friendly homeowners are likely to choose recyclable filters. They are changing disposable filters frequently, i.e., after every three months as advised ad up in terms of waste. Once you take out the old filter, recycling and disposable choices are restricted in several parts. Instead, washable filters are a more eco-friendly choice as they can be reused again and again for a standard of 5-10 years.

Cons of Washable Furnace Filters

Air Filtering Effectiveness

Washable air filters don’t have a clear image for air purifying functioning and have a standard MERV rating system between 1 till 4. They operate correctly at trapping massive flying pollutants like dust mites, dust, carpet fibers, and pollen. More significant disposable filters for domestic HVAC systems provide enhanced competence, up to a MERV ranking of 12. This best-quality of disposable choices can traps up to 95% of minor elements comprising bacteria, pet dander, and mold spores.

The one vital benefit in connection to recyclable filters is that they can be cleaned, washed, and reinstalled as frequently as you want. This can help reduce the quantity of mold and mildew development on the filter itself.

Maintenance Time

Both kinds of filters need some systematic repair and maintenance. Where disposable air filters need to be changed after every 30 to 90 days, the recyclable filters need cleaning and proper washing. This can be a little more time-consuming than just eliminating the old filter and inserting into a new one.

Comparisons with Air Filter

A Washable Electrostatic Air Filter vs. Metal Mesh

To support why a washable electrostatic air filter may be the perfect option, relate it to your usual Metal Mesh filter. A Metal Mesh air filter depends on numerous layers of emitted or extended metal attached to a pad to trap wreckages. A spray-on tackier is required to raise the competence and usefulness of this sort of filter.

A washable electrostatic air filter, though, is comprised of woven polypropylene channel with electrostatic characteristics that increase element trapping. This electrostatic charge keeps flying elements out by illustrating them onto its woven fiber surfaces, similar to iron filings onto a magnet. Since stagnant electricity leftovers are consistent over time, these filters will never miss their electrostatic features, irrespective of how long they are used or how frequently they are cleaned.

A Washable Electrostatic Air Filter vs. a Disposable Filter

Since an electrostatic air filter is washable and recyclable, you no longer have to keep a heap of disposable filters convenient for monthly replacement. Instead, you eliminate your washable electrostatic air filter, wash it with water and perhaps a little detergent, and then put it back in its original position.

The filter won’t split either, as the petroleum-based channel has brilliant power and is remarkably resilient to scratches. Moreover, a recyclable air filter states the environmentally friendly issues of disposable air filters.

You may have studies that washable air filters don’t always operate up to the same competence principles as disposable filters. That may be true when compared to some of the high-efficacy, element dimension specific to MERV rated or HEPA filters out there, but they leave behind the metal mesh filters. Mainly, washable air filters are used as a pre-filter for those great proficiency filters, capturing big particles and allowing post filters to function more competently.

Wash well until no detergent is coming out of your Filter and shake off extra water.

Where to Buy Washable Furnace Filters Online?

Also, for the sake of your ease and comfort, Amazon sells the best washable filters that have the best customer reviews from reliable producers. Delivery is often quick and free.

Do I Need Measurements Before Ordering?

Yes, you’ll want to calculate and measure your old filter and look for the one that will fit accurately. Keep in mind that the production average for disposable filters has traditionally been destabilized by 1/4″ to 1/2″, making it small size. This means when you take hold of a 16″ X 25″ disposable filter off the shelf at your nearby hardware store, it could be nearer to 15.5″ X 24.5″.

In most situations, you should be capable of using the closest typical size. Washable electrostatic furnace filters have a rigid and inflexible metal or plastic frame. So you may need to order an exact and accurate size to ensure it slips in and out of your filter record easily. You may want to calculate the channel opening using a flashlight, and a rigid duct tape calculate.

Look inside the part of the furnace where the filter should be placed. You should have a 1″ filter record or opening where the filter slips into. Calculate the height and width of the duct opening. You can also contact customer service or your local HVAC service provider, and they will help you control which filter size you should order for your special furnace. Always double and treble check to get an accurate measurement of the furnace filter when you call. There’s nothing lower than having to wait for the exact size when you’ve received the wrong size.


Managing and maintaining a clean filter is necessary, but the expense of disposables can begin to add up, not to state the waste stacking up in landfills. Our preference for washable furnace filters can compensate for themselves over some time while reducing undesirable waste.
