I was very impressed with the prompt delivery time of the filters and the ease of ordering online. I had used another online supplier in the past and had to cancel my last order due to two delays in shipping.

Haven't tried them out yet, but the boarders seem to be stronger than the Arm and Hammer ones I bought at Home Depot. Those started to colaspe after just a couple of days, and they never came near water.

I ordered the HVAC filters and they arrived timely and was exactly what I wanted. I also purchase my refrigerator water filters from this company and have been very pleased with the affordability and the excellent standard o the products they sell.
