Customer Reviews
Great value on multi-pack
This was my first time buying from here, and I needed new filters for my Whirlpool. I saw they had a good deal on the EveryDrop Filter 1 when you bought more than one, so I went for the 3-pack. It saved me a good chunk of money compared to what I usually pay at the big box stores. Shipping was free too, which was a nice bonus since my order was over $50. Felt like a smart purchase and I definitely got good value.
Filters arrived, one small issue
I ordered two Frigidaire PureSource 3 filters. They came well-packaged and seem to be of good quality, just like the originals. Installation was straightforward. The water tastes clean, so they're doing their job. My only minor gripe was that shipping took exactly 6 days, which was a bit longer than I expected for standard shipping these days. Not a deal-breaker, but something they could tighten up. Still, the price was right, and I got what I needed.
Consistent quality and service
I've been getting my LG LT1000P compatible filters from National Filter Warehouse for a couple of years now. This last order was just as smooth as the previous ones. I always get the multi-pack to save a bit, and they arrive pretty quickly, usually within a week to my place in California. The filters always work well and last as long as expected. It's why I keep coming back instead of checking other places.
Easy to find filters, shipped fast
I got a couple of GE MWF compatible filters from here a few weeks ago. My fridge needed new ones, and I always forget the model number, but their site made it really simple to figure out which ones I needed. They got to me in about 4 days, which was pretty good. Price was decent too, especially for the multi-pack. Overall, a good experience.
Fantastic filters, definitely recommend!
Wow, I just got my Kenmore 46-9690 filters and I am so happy with them! They fit perfectly and the water tastes amazing now. The ordering process was super easy, and they arrived right on time. I got the subscription discount too, which is just brilliant for saving some extra cash. I'm telling all my friends who need filters to check this place out. Will absolutely be ordering all my future filters from here!

Anyone know how long shipping usually takes to, like, Phoenix, AZ? Need a new filter ASAP before my water starts tasting weird.
Hey guys, thinking about grabbing some filters from here. Are these like, actual brand filters or knock-offs? Don't want to mess up my fridge.
