Easy to change, although I opted to have a 2nd pair of hands as it was my 1st time changing the 6 month filters. Will purchase again.

Pretty good filters. We have pretty hard and polluted water with insecticides and pesticides. The filters work good, but have to be vigilant on changing them.

Good Filter System

We've enjoyed our RO system for several years now. Being able to purchase the filters in bulk is great; we always have replacements on hand. If you don't have an RO system (or some kind of filter system) here's your sign. Easy to install, use, and maintain.

A++

Installed the unit on basement wall directly under kitchen sink. Also incorporated connections to the refrigerator thus eliminating constant water filter changes. Next thing best to a distiller - best tasting water by far. Saved a ton of money despite yearly membrane and filter changes. Purchased another unit for my son.

Great filters, but...

There are also consumables that may need to be replaced. Things like the little e-rings which hold the connections secure, or even some of the connectors. I have found no way to resupply these items, including those handy wrenches, even as an option.

RO Filters

From researching Express Waters website to determine the correct filter replacements to ordering, delivery and installation the experience with Express Water is fantastic. One of the best companies to do business with. The filters quality is superb guaranteeing great tasting, safe water.

Double Gift

I usually buy a 2 or 3 filter set when it's time to replace mine. But since my sister and a friend of mine recently got water filtration systems of their own, I decided to buy this 10-set and share the filters 4-4-2 among the 3 of us. So far, they haven't had anything bad to say about it. But I've been buying these filters for years, so I was already expecting that (kind of the reason why I bought it as a gift in the first place lol...)

Qiuck Install

I purchased this replacement set for my Express Water 5 stage RO system. It comes with 5 filters. 3 of them you have change about every 6 months, and 2 of them are replaced yearly. Fotunately replacing my old filters was easy and simple. I have my Reverse Osmosis System under my sink so I completely turned off the water supply there. Then you have to remove the 3 housings on the bottom (use a wrench if you need to). Also make sure you spread some towels out below you, because there is still some water in the housings. Then, remove the filters from the housing after you removed the housings. Clean them and make sure all the rubber parts are still where they're supposed to be. Then put the new filters in the correct order back into the housings, and re-attach the housings to the system. You can turn on the water supply now if you'd like, unless you want to replace your post filters too (those are the ones that last a full year). My old post filters are still fine. Later I'm going to buy a TDS meter to really test my water, but so far it tastes great. In summary, installation was easy and the filters have been great so far (Btw this should apply to most systems, but I did this on my Express Water model)

Don't forget to replace!

I somehow never learned that every water filter has a life span. I mean, it should be common sense. But after our water starting stinking, it hit me that maybe I had to buy new ones! Better late than never, I guess. They sent it out quickly and replacement was easy. So now my water is just as good as before.

Easy Installation

It was pretty hard getting the Reverse Osmosis System installed the first time, and I wasn't looking forward to replacing the filters when the time came. Well, the time came and luckily it was pretty easy this time. Something usually goes wrong when I try things like this but it was all smooth this time around.

Review of RO system

RO system works great. Very easy to install. Detailed instructions provide the information needed that a ***** like me could install with no problems or leaks. The replacement filters are also very easy to install too. Shipping is very fast. Excellent customer service. No problems with the system at all. Well worth the small investment.

Review on replacement filter elements

The filters work great. My humidifiers, ice maker, coffee pots and so on all remain clean and clear. Water and stuff made with the water all have a better taste. Replacement filters were color coded for easy correct installation and the entire ordering and installing event went as easy as could be imagined. Good stuff.

Sanitizing and replacing RO filters .

I removed all of the old filters washed each Container then I sanitize the system with a nun coronated sanitizer. I then replace the old filters with new ones and added 8 wonton disinfectant polishing cartridge. I am extremely satisfied with the system!

Extremely Satisfied Customer!

I purchased my 6-Step system back in June of 2016, and every step of the process was smooth and satisfying. I began with online research, after which, selecting Express Water was pretty much a no-brainer due to the great, low prices in spite of what appeared to be very good-quality products. Although I could have ordered via eBay, I had a couple questions so I called Express Water directly. The gal was very knowledgeable, answered all my questions, and then sold me the system I was interested in (didn't try to 'upgrade" me to spend more $$$) and, with the sale they had going on plus an additional 10% off that she gave me, I got my system CHEAPER than the eBay price! I have since restocked with new filters and had the same experience. Not only did they hook me up with the most economical option (a 2-yr. supply, in this case) but then, again, gave me an additional 10% off the sale price! My replacement filters, including the UV bulbs, cost me less than $70/year . . . that's like . . . $5.50/month!!!! Love these guys!!

Great R.O. systems.

When we purchased this R.O. system, we also purchased a water tester. Not only did the water test near perfect, but it gave us peace of mind that were were not ingesting all the contaminants that are in most municipal water supplies. Great product and good price. Well worth the money!

EXCELLENT VALUE

This is my second year of using the express water filters. I am so glad I no longer use the local branded water filtration systems. I also tried the big department store systems, but was shocked at the refill prices. The filter pack is designed for simple installation.
