2. iSpring RCC7AK Under Sink Reverse Osmosis Water Filtration System Review
The iSpring reverse osmosis water filtration system sits easily under your sink, and it takes minimal effort to install. The water comes out with a crisp, clean taste and substantially cleaner.
This system is well-loved for two primary reasons. First, it’s extremely quiet, and secondly, the system operates smoothly with normal water pressure levels. It delivers quality purification, although slightly less alkalinity than the Home Master model above.
With 75 gallons of reverse osmosis processed water a day, this can handle the needs of most small households. The installation is extremely easy although you will need to run your local hardware store for some basic hardware supplies. We recommend you replace the O-ring as well.
Once installed, this system continues to produce high-quality, great tasting water.

3. Apec Top Tier 5-Stage Reverse Osmosis Water System Review

5. Apec High-Flow 90 GDP Reverse Osmosis Drinking Water Filter System Review
Another Apec product makes our list with their High-Flow 90 GDP model. Apec still offers their 30-day money-back guarantee, 1-year warranty and lifetime technical support from certified water specialists. But, this model is a bit different. It’s slightly larger but is a great option for large water needs.
If you have a large family or prefer to use your drinking water for your cooking as well, consider this option. The faster flow capacity allows the water to pass through the filters faster and results in longer filter life. Although the faster flow capacity does mean that the system isn’t as effective as other systems.
The Apec high-flow model can produce up to 90 gallons of reverse osmosis processed water a day. Take note that the system is difficult to install, and you might need a plumber.

Avoid – General Electric PXRQ15RBL Reverse Osmosis Premium Water Filtration System Review
General Electric delivers a 3-stage reverse osmosis drinking water system. Unfortunately, the price tag has fooled many into believing that the model is a top-of-the-line product.
Of the common complaints, installation is the most irritating. Many people purchase a reverse osmosis drinking water system believing it is an easy DIY project. GE’s PXRQ15RBL water filtration system requires a plumber, and you can avoid damage to the system and your counters by calling a plumber in first.
Another complaint is the noise level. As the General Electric’s water system fills, it’s tank it omits a loud gurgling sound. This noise is loud enough to hear multiple rooms away. General Electric is known for refusing to either replace “defective” products or accept returns.

Avoid – Geekpure 5-Stage Reverse Osmosis Drinking Water Filtration System Review
The Geekpure 5-stage filter seems to deliver all the basics that you can expect from a reverse osmosis drinking water system. However, it quickly falls short on quality and results in water waste.
While there are allegations that the system wasted about 300-gallons of water in a day, it seems a bit farfetched. Although there are many reviews which cite water waste as a concern and issue that required repair.
The water waste cited by the Geekpure, however, is due to leaking. Not only is this wasting water but it’s causing damage to your kitchen. There are constant complaints with the Geekpure reverse osmosis drinking water system that the filters, fittings, tubes, and even faucet don’t fit each other.
You expect a system to work straight out of the box, but if fittings don’t match, or connect well, call it quits and dial customer service.

2021 Buyers Guide to the Best Reverse Osmosis System
The popularity of reverse osmosis spiked because people prefer knowing that their water isn’t just “purified” but essentially cleaned. Whereas water softeners are intended to remove heavy metals, and water purifies remove some harmful chemicals, a reverse osmosis drinking system removes harmful products with a system that’s beneficial to your health. People know that this process works and that it’s used by top brands to offer health benefits as well as hydration. Additionally, some water drinking systems will create an undesirable taste effect, but with the best reverse osmosis drinking water system, the actual quality and flavor profile should improve. To narrow in on the right ro system, here are three key points to consider.
3 Main Points to Consider:
- Type of Membrane for Quality: Knowing the current level of quality that your water comes out of the faucet at will help you identify which membrane is right for you. For instance, if your tap water is chlorinated as most tap water is, you should use a cellulose triacetate membrane. These membranes resist chlorine more effectively than other membrane options. However, if you’re using well water, which may not have chlorine, you should use a TFC membrane. A TFC membrane guards against more bacteria.
- Installation: Many people don’t want to call a plumber for any reason, especially to install a simple reverse osmosis water drinking system. However, most reverse osmosis water drinking systems require a bit of confidence in DIY projects, home improvement, and handling tools. If you’re confident and have taken on minor DIY projects before, you can install a good system without issue. Where installation goes wrong is when the unit’s tubes, fittings, and faucet don’t work well together. Read through reviews to ensure that you’re not going to have mix-matched parts when you open your box.
- Stages of Filtration: Reverse osmosis water drinking systems rely on at least 3 stages to achieve the reverse osmosis process. However, many of these systems have 4 or more stages for additional purification. If you know your water quality is exceptionally poor, invest in a 7-stage system. However, if you are simply looking to increase the current quality of your drinking water a 3 or 4-stage system will work well. As you dig further into which system is right for you, the membrane may help determine how many stages of filtration you need. If the membrane caters to one issue in your water, you may need another filtering stage to address other concerns.
Is it safe to drink reverse osmosis water?
Yes, many bottled water companies use reverse osmosis to remove as many chemical, biological and metallic properties as possible before bottling.
Reverse osmosis removes unwanted minerals and chemicals which helps your water taste cleaner too. It also removes bacteria and viruses. There is no indication that removing any of these can cause adverse health effects.
Because many mineral and chemical compounds are added to our tap water, removing them restores it to its most simple form. Well, water, however, can encounter contaminants through the ground. Iron, arsenic, radium, sulfate, lead, copper and chromium are all known to infiltrate well water through the ground.
Using a reverse osmosis drinking water system and removing these hazards is a safer drinking option than leaving the water unprocessed or simply filtered.
Is reverse osmosis water the same as purified water?
Reverse osmosis is a process that coincides with purification, but they are different. Purified water takes well, or tap water then passes it through a few filters. Reverse osmosis is another process where the water is pushed in a direction opposing standard osmosis; this membrane creates a pressure which allows only water particles through.
In the end, reverse osmosis cleans the water more effectively than a series of filters. Most reverse osmosis drinking systems are highly effective but still, contain multiple layers of filters. These filters are before and after the reverse osmosis membrane to ensure that all contaminants, chemical or biological are filtered out.
Do reverse osmosis systems waste water?
Yes, unfortunately, reverse osmosis systems do waste water, and sometimes they waste a lot of it. Most reverse osmosis drinking water systems immediately dispose of the water which contains contaminants. When you have this type of system, you have no access to the water and lose complete use of it.
However, some models do offer the versatility sought out to use the unwanted water for other things. Many people use the water for gardening and cleaning. If you are concerned about the water waste, make versatility a top priority feature.
