I've always had trouble installing air filters, regardless of the brand. I'd have to push and bend the edges, but this brand is different. It slides right in and fits perfectly. The only downside is that I didn't see any directions. I tend to get confused easily with the arrows.

Better air quality
Air filter is of good quality. My allergies have improved greatly since installing this filter in my system. The price was fair and it was delivered in only 1 day. Great buy and would recommend it for allergy sufferers and pet owners. I will be purchasing again in 3 months. Thanks!

Great quality air filter, fit perfectly and sturdy. It is premium quality compared to the 3M ones, and cheaper than the equivalent 3M.. Thank you FilterBuy.

Great furnace filter
This is a nice furnace filter. It filters out really fine particles. Fast delivery easy to install. Highly recommend

Great price for a good filter
I'm tired of paying a premium price for an average furnace filter just because of the name brand. These work as well as the costly 3M brand for half the price (on sale).

Cheaper than other brands
It's cheaper than other brands. And I hope it works well.

DO NOT BUY THIS
The filter material is substandard. The filter barely meets measurements, 19.85 inches X 20 inches. The filter material is also sub par. For the price one would expect 2 filters, you only get 1. I don't think I have EVER been more disappointed in a purchase from Walmart. That they would sell a product this bad is truly upsetting.

Was damaged in transit due to packaging of items. Much larger box than needed and items moved around easily. Causing a glass jar to open and its contents spilling out onto air filter rendering it unusable
