It took a while to get here. Price and product were great

Quick delivery after I placed the order. Always prompt response of my phone calls to Tech Support. I especially appreciate all the help from Peter for phone support he provided. He patiently stepped me through the setup of my new water softener.

Excellent

Received timely. No problems.

Easy to order. Good price.

Seamless

Our family has been using Tier1 filters for the past 8 years. We purchased a water filtration system for our upstairs and to get help figuring out which one would match us best I called their number. Peter has been helping me, and has patiently gone out of his way to present me the options and to explain the pros and cons. He has been kind and easy to get a hold of. This was one of the best customer service experiences I’ve had…I felt like I was genuinely cared about. I am very satisfied with Tier1 because of the high quality filters as well as the top notch customer service I’ve experienced

Shipping and cost plus product all great.

Shipping was good and if you need to return something they don’t give u any problems 😊

Fast delivery

Perfect fit.

Will buy again and recommend the my friends.

The Cartridges work perfectly - I have no complaints, at all, and I have already used two refills in the past - too, bad the company was having, or did, have stocking problems, but I guess it is the times we live in - fortunately I always am one step ahead and order way before I run out.
