I wanted a higher Merv filter for viral concerns. I wanted to keep our circulating air as clean as possible. I feel there has been an improvement. Less sniffing and allergy symptoms. Even if I have some when were outside as soon as I come back in and the filter cleans the air ny breaching improves quite a bit. Works for me.
Weve been so pleased with these filters. Its amazing the decrease in the amount of dust we saw with other filters and how much better the HVAC systems run. Amazing.
These filters seem to clear the air quite well and the price was great! The only minor detail that I didn't like was that my entire year supply came in one big package. So once I opened it the rest of the year's filters are exposed. I would have preferred individually wrapped. But, at these prices, that's a very minor issue.
Not only do I buy these filters for my home, but also for my son's home because he has an unusual size and allergies. The filters are exactly as described and they ship quickly. Thank you.
