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 16x20x4 filter in your Honeywell unit you should order our 16x20x5 Honeywell Replacement air filter that measures 15 7\/8 x 19 3\/4 x 4 3\/8 (15.88x19.75x4.38).\u003cbr\u003e\u003cbr\u003eIronside 16x20x4 \u003cb\u003ePlus Carbon Air Filters MERV 8\u003c\/b\u003e are made of a dual material where the MERV rated material has been fused together with a carbon layer. This results in less flow restriction and 33% more surface area for cleaner smelling air. It will help eliminate unwanted odors as well as trap most airborn dust and particle matter for fresh, clean air. Odorus gases and vapors (VOC) are attracted to and held by the activated carbon material while maintaining excellent air flow properties. With each pass through the carbon furnace air filter, the air in your living environment improves. Each time air passes through an Ironside pleated furnace filter, lint, household dust, pollen, dust mites, pet dander, bacteria, 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 carbon AC filter media prevents the growth of bacteria or mold, resulting in a much healthier living environment.\u003cbr\u003e\u003cbr\u003eMERV 8 furnace air conditioner filters are comparable to HVAC filters with the rating of MPR 800. Particles in indoor air are measured in microns; for scale, a human hair is about 70 microns wide. Each Ironside 4” MERV 8 air filter captures airborne particles as small as 3.0 to 10.0 microns. 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\u003eCaptures large airborne particles like lint, household dust, pollen, dust mites, mold spores and other contaminants.\u003c\/li\u003e\n\u003cli\u003eIf you are replacing a Honeywell or Lennox 16x20x4 Plus Carbon or an air filter with an MPR rating with an actual depth of 4 3\/8, please see our 16x20x5 (4 3\/8 actual depth)\u003c\/li\u003e\n\u003cli\u003eHypoallergenic, antimicrobial, and electrostatic filter media.
