{"product_id":"20x25x4-merv-13","title":"20x25x4 MERV 13 Air Filter","description":"\u003cp\u003e\u003cb\u003eImportant Note:\u003c\/b\u003e Almost ALL furnace filters have a different \"actual size\" than the nominal size printed on the air conditioner filter. It's best if you measure your air filter for the EXACT size and compare it to our \"Actual Size\" - and then you can be sure your A\/C air filter fits! With the 4\" and 5\" air filters there is a wider variance between the nominal and actual size depending on the manufacturer. If you are replacing a 4 3\/8 depth 20x25x4 filter in your Honeywell unit you should order our 20x25x5 Honeywell Replacement air filter that measures 19 7\/8 x 24 7\/8 x 4 3\/8 (19.63x24.88x4.38).\u003cbr\u003e\u003cbr\u003eIronside 20x25x4 \u003cb\u003ePleated Air Filters MERV 13\u003c\/b\u003e are made of electrostatically charged synthetic materials that attract and capture most airborne particulates in your home. Each time air passes through an Ironside pleated furnace filter, lint, household dust, pollen, dust mites, pet dander, smog, smoke particles, virus carriers, bacteria, allergens, mold spores and other contaminants are removed. All Ironside pleated air filters are manufactured using a heavy duty, moisture resistant beverage board frame. There is a metal mesh support grid bonded to the pleats for extra support. Our AC filter media prevents the growth of bacteria or mold, resulting in a much healthier living environment.\u003cbr\u003e\u003cbr\u003eMERV 13 furnace air conditioner filters are comparable to HVAC filters with the rating of MPR 2200-2400. Particles in indoor air are measured in microns; for scale, a human hair is about 70 microns wide. Each Ironside 4” MERV 13 air filter will capture more than 90% of 1.0-10.0 micron contaminants and up to 75% of .30-1.0 micron contaminants. This high-performance HVAC replacement filter will outperform non-electrostatic fiber-glass filters, washable filters, poly disposable filters, and will help keep your air conditioning and heating systems running efficiently, saving money on utilities and costly maintenance.\u003cbr\u003e\u003cbr\u003eThe effective life of your AC air filter depends on both the inside and outside conditions in which you live. It is important to regularly change your furnace air conditioner filters especially during any home improvements for fresh, clean air in your home or office. We recommend that you change your air filter every 3-6 months to maintain maximum efficiency and economy.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eRemoves lint, household dust, pollen, smoke particles, dust mites, pet dander, virus carriers, mold spores, smog and other contaminants.\u003c\/li\u003e\n\u003cli\u003eIf you are replacing a Honeywell or Lennox 20x25x4 or an air filter with an MPR rating with an actual depth of 4 3\/8, please see our 20x25x5 (4 3\/8 actual depth)\u003c\/li\u003e\n\u003cli\u003eHypoallergenic, antimicrobial, and electrostatic filter media.
