Great product. Filters the air real well with a perfect fit. Add to that great customer service! My refill order had gone to a wrong address in another state due to my error. Customer service said no worries. The receiver can just donate them and they'd send replacement to correct address at no charge. They also have quick delivery and notify you so you can track it.

I appreciate the quality of this filter and the price couldn’t be a better buy. I like that I can stock up and get a great price the more you buy. This company is by far the best to purchase from, they stand behind everything they sell and respond quickly if there is an issue.
