Customer Reviews
Good value for my fridge filter
I needed a new refrigerator water filter and searched around quite a bit. Tier1Water had a good price on a multi-pack, which made the per-filter cost much lower than other places. Free shipping on orders over $50 helped too. It felt like a smart purchase and the filter works fine.
Love my new shower filter!
Oh my goodness, I just got the shower filter and already I can tell a huge difference! My skin feels so much softer after just a few uses; it's not dry and itchy like before. Installation was super easy, too, took me like 10 minutes. Will definitely be telling all my friends about this. So happy with my purchase!
Reliable filters, good service
I've ordered my replacement filter cartridges here for my whole-house system a few times now. They always fit perfectly and arrive within a week, even to California. It's nice not to worry about it.
