Customer Reviews
Good filters, good price
Needed a new sediment filter for my whole house system, and WaterFilters.net had a good selection. Found the right one pretty easily. Shipping was standard, nothing crazy, took about a week to get here. The filter seems to be working fine, no complaints. Water pressure is good. Overall a solid experience, I'd probably order from them again when I need more stuff.
Great value on new system
I was looking for a new reverse osmosis system and compared a few places. WaterFilters.net had a 'whole house system sale' going on, which saved me a decent chunk of change compared to other sites. I also got free shipping since my order was over $99. The system itself was exactly what I needed, and the installation wasn't too bad. For the price I paid, it felt like a really good deal. Definitely felt like I got my money's worth with this purchase.
Decent purchase, one small hiccup
I ordered a few inline water filters and a new pressure gauge. The filters arrived quickly, in about 4-5 business days, and were exactly as described, NSF certified which was important to me. However, the pressure gauge wasn't in stock, and I had to wait an extra three days for it to ship separately, which wasn't ideal for my project timeline. Customer service was helpful when I called about the split shipment, explaining the delay politely. The products themselves are good quality, and the prices were competitive, especially with the multi-pack discount I found. Just wish everything had shipped together.
Excellent filters, fast shipping!
I just got my replacement water filters for my under sink system, and they're perfect! Everything arrived super fast, like 3 days to my house in Arizona. The filters fit great and the water tastes amazing again. Definitely shopping here for all my future filter needs. So glad I found this store!

Hey, thinking of grabbing a whole house system. Are the filters actually legit, like NSF certified and stuff? Don't want to buy some knock-off.
Anyone know how long shipping usually takes to, say, California? Need a new fridge filter kinda urgently.
