Sentry Water Filters + Reverse Osmosis Avis 

Marlon was super helpful with helping to identify the right filters for our icebath, and then when I accidentally ordered 1 instead of 6 they quickly rectified the order without any fuss. Will be ordering from here again soon.

Sentry water filters plus Reverse Osmosis provided outstanding service, guiding me through whole house water filtration and Reverse Osmosis options. Marlon and Liz expert advice helped me choose the perfect system for my home based on my needs. They even have a list of experienced recommended plumbers to do the job if you don’t have one. Thank you again Sentry Water Filters for your commitment to excellence. I highly recommend their quality products and service. My whole house and RO filtration system is up and running and very happy with the outcome. You have a customer for life!

Super quick delivery with clear communication all the way

Great reverse osmosis 7 stage water filter. Love drinking clean water straight from my tap.

Great product reasonable price comparing to market water quality , forget about the tap water

Marlon bent over backwards with extremely good customer service. Thank you

Great service, order arrived within a few days and was exactly what I ordered.
Couldn't ask for more!

Good service and value as always.

Magnesium filter is vital part of my rain water system for drinking water. Good value and service, thanks

Had a couple of teething issues which were handled with no fuss and very quickly. System now works great and does all that I was told it would.

I was looking for a RODI system that wasn’t costly like from your local fish shop for my marine tank and I came across Sentry! Set up and instructions was very detailed and a breeze.. and for one that’s learning about the system I felt supported and educated even though it was self set up! I’m a happy customer and so far my tank is happy!

Outstanding service, always good advice. Buy from these folks anytime

I thought it would be daunting to use the filter but they provided everything I needed and it was all clearly labeled. It was received quickly and packaged with care. I highly recommend purchasing from them

Love my filters feel safe drinking the water. Wish it bought them sooner for our water tank it would of saved me from getting sick. Picked up a E.coli from drinking tank water that has no filter.

Replacement filters delivered within 24 hours. They were numbered as well to avoid any confusion on my part during replacement of my 6 filter system which was welcomed.

Correct item delivers promptly and sold at the right price.

Great advice in the purchasing phase and after support for easy filter replacement, quick postage and great quality products.

Fast postage and emailed back fast. product was nice.
