This company is a scam
This company is a scam. They sell air filters rated by them as Merv 13. However, their filters are more like Merv 1. I send them pictures of Merv 11 (I bought from a different company) vs their Merv 13> The pictures clearly shows the scam this company is running. They offer me to ship the filters back on my own dime and then they'll refund my purchase. Based on reviews from other customer they don't refund the money so I'm not going to spend another dime on these scammers. I wish I had read the reviews before my purchase.
