Customer Reviews
Great value on new filters
This was my first time ordering from here. I was looking for a good deal on some under sink water filtration filters and found a decent discount. I compared prices with a few other places, and Tier1Water had the best offer, especially with the free shipping since my order was over $50. The filters arrived quickly and were easy to install. The water quality is noticeably better, and I feel like I got a really good deal for what I paid. Definitely felt worth the purchase.
Reliable filters, consistent quality
I've been buying my refrigerator filters from Tier1Water for a couple of years now, even after the move to DiscountFilterStore. This last order was for a couple of replacement filter cartridges for our whole-house system. They arrived in about 4 days, which is pretty typical. The quality has always been consistent, and I haven't had any issues with fit or performance. It's why I keep coming back; I know what to expect and they deliver.
Good filters, shipping could be faster
I ordered a multi-pack of refrigerator water filters for my Samsung fridge. The price was good, especially with the multi-pack savings. Installation was straightforward, and the water tastes clean. My only real gripe is that shipping took almost a week, which felt a bit long. Customer service was responsive when I inquired about the tracking, so that was a plus. Overall, a solid choice for filters, but plan ahead for delivery time.
Quick delivery, good product
Ordered an ice maker filter. It arrived in four days. Easy to install. Works as expected. Very satisfied with the purchase.
Detailed feedback on whole house system
I purchased a whole house water filtration system after doing a lot of research. The ordering process was fairly smooth on the DiscountFilterStore site, though navigating the different system options took a bit of time to understand completely. I called customer support with a few questions about installation and they were helpful. The system took about a week to arrive, which was within their estimated timeframe. Installation was a weekend project, and the instructions were clear enough. After a month of use, I've noticed a significant improvement in water quality throughout the house – less chlorine smell, and my skin feels better after showering. The replacement filter cartridges seem reasonably priced. My only minor suggestion would be for more detailed 'how-to' videos for DIY installation on the product page itself. Overall, a solid product and experience.
Got my shower filter, all good
Needed a new shower filter so I hopped on the site. Found one pretty easily and checkout was smooth. It got here in like 5 days, which is totally fine. Installation was a breeze, just screwed it on. Water feels a bit softer now, so that's nice. No complaints, just a simple purchase that worked out.

wondering if these are legit or just cheap knock-offs. The prices seem pretty good compared to like, Brita or something.
Hey, thinking of getting a whole house system. Do these filters actually last, or am I going to be swapping them out every other month?
