In my personal opinion, HEPA filters are definitely worth the money if you want to put them in your home’s HVAC system. It’s really important to make sure that the air filter that you use in your heating and cooling system is the right one for your home. Some people need to use allergy reducing air filters, to keep the indoor air quality in their homes at the right levels for them. When you are trying to decide which sort of air filter you need for your HVAC system, make sure that you get one that works for your family’s specific needs. If you suffer from different kinds of allergies, you might want to invest in an allergen reducing air filter. Either way, though, I suggest that you use a HEPA filter. HEPA filters are well known for their ability to get most of the offending particles out of the air in your ventilation system. If you go the cheap route and buy air filters that aren’t as good, you might save a little bit of money but you run the risk of having air quality that’s not as good as it could be. I personally think that it’s worth the money to buy higher quality air filters to go in your A/C and your heating system. I know a lot of people like to buy cheaper ones, but they don’t last as long and they really don’t keep your air quality at the levels that you should be breathing. In my opinion, HEPA filters are definitely worth the money.
