Review: Not a Difficult Filter-Switch - This filter has been an excellent product for me, and its' been great to not have to schlep all those water bottles. The only drawback was dreading the filter change that has received not insignificant reviews about the difficulty of replacing the filter. Replacing the filter on mine turned out to be a non-event. Specifics to follow: The common complaint is that the unit is hard to "crack" open, or break the seal allowing the unit to be unscrewed from the base. The first step in that process is to disconnect the black tubes from their connections. Next, drain as much water from the unit as possible. My process was to put a folded bath towel on the kitchen floor, securing the unit between my knees. With the plastic wrench (provided with the original unit) on the outer casing, and bearing down on the base to prevent rotation, steady, firm pressure resulted in immediate rotation of the casing away from the base. The seal was snug, but not so secure that it needs to be wrestled or "cracked" to release. (Disclosure: I'm a 5'11" male w/fairly sturdy but not exceptional build. A tinier or more delicate frame may have more of a challenge.) So mine was a non-event. That said, assuming these are primarily hand assembled or done with some mechanical assistance, there probably is variability in how torqued each particular unit may be. Point being, my experience represents only my unit, which surely isn't universal. But ... I continue to be pleased with the unit, new filter, and overall experience. I give a strong "buy" recommendation.
Review: BEST SINGLE FILTER I'VE FOUND - I replaced the KX MATRIKX Pb1 which had a bad taste to it. I have had the Ispring countertop water filter for over a year now and after trying several filters, I decided to spend a little more and get one that had more filter media in it and also makes the water more alkaline. It was easy to install and the instructions say to run it 2-3 minutes which I did. It makes the water taste great and my GF also notices the better taste and like it better than the other one. They also say it will last a year which is a plus, as others have said, less than $4 a month, so I will replace this filter with a new one in a year from now. Very good water. NOTE; DO NOT drink this kind of water with a meal. Like soda, it will lower your stomach acid and make it harder to digest your food, so you get even less nutrients than what little is in the food.

## Features

- Very easy to install 💧 No need for a plumber to replace this water filtration system cartridge. Simple twist-on installation makes it easy to set up. If there is any difficulties switching out the apex replacement countertop cartridge on the MR-1050 water purifier, contact us, APEX EXPRT's technical support will try to diagnose and provide additional assistance to complete your installation and get you your filtered water. * Reemplazo para purificador de agua
- Better tasting water 💧 The five stages of this sink water filter effectively reduce the most common impurities found in tap water, such as sediments, hydrogen sulfide, chlorine, chloramine, and other harmful chemicals. It also reduces heavy metals such as lead, iron, and mercury to ensure the water tastes great and is clean & healthy. *El mejor filtro de agua para cocina.
- Much better water quality 💧 Once the water has been filtered with KDF-55 (heavy metal reduction media) and a charcoal water filter (coconut shell, healthy minerals such as calcium, magnesium, and potassium are added to enhance the water's pH level to alkalinity. ⭐ NOTE: This countertop water filter system does NOT lower TDS or PPM readings. If TDS or PPM removal is desired, a reverse osmosis drinking water filter is required. * filtros de agua para tomar de cocina no baja TDS o PPM ⭐
- Worth the money 💧 No longer need to carry heavy cases of water bottles, water filters eliminate that need. Countertop water filtration can not only save you money, but it is the responsible choice to eliminate the millions of plastic water bottles. Buying bottled water for daily home consumption gets expensive. One water faucet filter cartridge can last up to 4-6 months. (This may vary based on the quality of the feed water).
- Great customer service 💧 Our water purifier under counter include a 30-day guarantee and 1 year manufacturer's warranty on defects in materials and workmanship. EXPRT's materials and components comply with NSF/ANSI Standard.

### ⭐⭐⭐⭐⭐ Lovely waterfilter
*by D***N on May 28, 2021*

5 star quality and service. I was shipped a bad refill cartridge. The seller replaced mine with no cost to me. I have been using this water filter for over a year. Pro's- - Water flow is the best. I cannot imagine one can get a better water flow out of a filter than this - Taste is alkaline and pleasant - Trouble free once hooked up. Switch between filter and regular tap is smooth and seamless - Owners/Sellers of Apex filter are very responsive to customers Con's - Because of the tight seal of the filter it is difficult to open for installing replacement filter. I think it is a expected that the seal will be tight for a high quality filter
