The best feature is how quickly these were received. Our usual vendor was backordered and Filterbuy was able to send them to us within 48 hours. Thank you so much!
I decided to try the Merv 13 filters due to dust in our home. We have kids and dogs and I could have dusted almost daily. The Merv 13 have cut it down to light dusting once a week. You can't beat that!!!
We live in the woods, with lots of garden around the house. There's lots of pollen in the summer, and dust and normal airborne allergens in the winter. We had all been sniffling, even the dogs! But I switched to these filters about a week ago and yesterday we commented that we are all sniffling less. I can only assume it's the filter doing its job!
With the addition of my putting a UVC light system in my HVAC system and your high quality and well priced HEPA filters, makes our family breath without the usual allergy sneezing!
