Unless you’re a knowledgeable homeowner or a licensed HVAC technician, you probably don’t know much about furnace and air conditioning filters. And that’s why we’re here! Read on to learn about some little-known facts about those handy dandy filters attached to your furnace or window air conditioning unit.
Little-Known Facts About Home HVAC Filters
- Pleated paper filters do little to actually adsorb and absorb fine particles and contaminants in the air, even though they’re the most commonly-used material used in the design of residential filters. Paper-based filters aren’t fine enough to reduce the small particles and pollutants present in the air.
- Most filter manufacturers test their own filters and assign them a self-imposed filter rating. We’ll let you decide if that’s an honest practice. (And, for the record, this is the exact reason we don’t include filter ratings anywhere on our website or on our filter packaging. We don’t believe it’s fair to our customers.)
- Paper-based pleated filters actually contain chemicals. Of course, most trees don’t produce wood that’s white or even off-white; to make up for that fact (and to keep the pleats ‘attractive’ or cohesive-looking), manufacturers dye the paper pleats. However, in dying the paper pleats, manufacturers actually add that dye chemical to the composition, and the filters will release those chemicals into the air as they are working.
- Most paper-based pleated filters do very little to reduce the allergens in the air. Think about it — paper doesn’t have the ability to reduce allergens by itself. The construction of a filter is just as important as the materials that go into it. Filters that are constructed to trap and reduce contaminants in the air by adding things like adhesive and activated carbon will greatly improve the effectiveness of their filtration process.
- Filters that don’t have activated carbon can’t effectively destroy the bacterium that is caught by the filter, and most filters don’t have activated carbon added to them.
- Trim-to-fit (or cut-to-fit) filters are available for purchase, and will enable you to fit a filter into just about any furnace or air conditioning unit slot. If you’re not sure what size residential filter you need, we recommend a cut-to-fit filter.
- The best filters can even reduce certain heavy metals from the air.
