Replacement HEPA Filters: Essential for Consistent Allergy Reduction & Noise Control

Most sinus or respiratory related allergies are the result of airborne dust, mold spores, pollen, hair and other pollutants commonly inhaled in homes and offices. And many allergy sufferers do buy an air purifier at some point and do get relief since some or most of the pollutants are being removed and they’re not breathing them as much. Some people, however, find that their allergies come back to a degree in a few months and they’re not sure why.
There are usually two causes of ‘returning allergies’ when you’re using an air purifier. First, obviously or not, if the filter is full, the airflow is restricted some and on the same fan settings, the unit cannot cycle the same amount of air as before—which means the clean air delivery rate has decreased and the unit is not cleaning the air as fast as it was when the HEPA filter was newer. This leaves more pollutants in the air for a longer length of time—which gives you time to breathe them before the air cleaner can get to them.
This is one of the main reasons it’s very important to replace your HEPA filters on time or before, especially if you have pets in your room frequently, or if you have recurring allergies. A clean HEPA filter will not only allow the unit to clean the air quickly, but it will also keep the noise down because a clogged HEPA filter usually increases the noise of the air purifier from that restricted air flow we mentioned. So if you’re air purifier isn’t as quiet as it used to be, you’ve probably got a clogged HEPA filter.
The other main reason that air cleaner-using allergy sufferers sometimes get a rebound of allergy attacks is that the normal level of pollutants has changed, from more dust or other pollutant regularly being added by foot traffic, something coming in through the A/C system from outside (pollen?), less vacuuming and mopping is happening, or new pets have been added—all of which can overload what the air purifier can remove in a given amount of time. If you have more pollutants, you may need more than one room air cleaner with a HEPA filter to keep the air being cleaned quickly enough so you don’t breathe the pollutants or allergens first.
Be sure your air purifier has a true, certified HEPA filter, too—HEPA-style isn’t’ the same and doesn’t remove as many particles. HEPA style air filters are often found on cheaper air purifiers and that may be an issue as well. Also check the output of your air purifier—if it’s less than about 150 CFM on he speed you like to run it on, you may need to increase the fan speed or get a HEPA air cleaner with a higher output. Your HEPA air cleaner filters are great for removing dust, mold, pet dander, etc., and keeping your allergies under control—but only if you replace them regularly and don’t overload them beyond the air cleaner’s capacity.
