Top Ten Water Filtration Systems For Home 2021
The word water filtration is an all-inclusive catchphrase but what it really means is filtering things out of water. Then when we discuss the top ten water filtration systems 2021 we need to decide if the filtration is for drinking or the whole house. For the purposes of this article, I will start out with drinking water and work my way up to the whole house.
Carbon Water Filtration Systems.
There are many on the market today that can be identified by a single-cylinder that sits on the counter or within a refrigerator. Carbon is great because it absorbs VOCs like pesticides and oils, and removes particulates. Two drawbacks to carbon are it will not remove small particulates and bacteria feed on it. So unless you are on a city supply where there is constant chlorination you will need carbon with silver-impregnated into it. The silver kills the bacteria and keeps the filter relatively safe for a limited time. My top picks are the Brita Filter and the Nu Aqua for cost and convenience.
Reverse Osmosis Water Filtration Systems
The reverse osmosis system is highly effective as it utilizes a fine filter that removes pretty much everything. It has 2 pre-filters consisting of carbon and a sediment filter and then a post-carbon filter to make the water taste ok after filtration. Just as in the carbon filtration system there is always the chance bacteria can grow within the filter and for the same reasons either change the filters as directed or move up to the next model. One big drawback to the Reverse Osmosis system is installation and service are tricky and better left to professionals. My top picks for reverse osmosis systems are Culligan at the top and Nu Aqua just behind it.
Reverse Osmosis Water Filtration With Post Ultra Violet Light
As I have previously stated one drawback to any system that does not have chlorination and uses carbon is still bacteria. Systems that utilize a post-Ultra violet light help to minimize the chances of bacteria reaching the tap. The major drawbacks are the same as the standard reverse osmosis system plus you need to change the light every year and it is expensive. My top picks for this category are the Bluonics 7 and the I Spring respectively.
Bottle less Water Coolers
There are many bottle-less water coolers on the market and they are great and even deliver a higher quality of water to the end-user than most bottled waters. Many simply use carbon and particulate filtration system but a few use reverse osmosis. Personally, I like the Reverse Osmosis system, but one drawback is low PH since it squeezes all the calcium right out of the water. There are systems that follow up the RO process with a final calcium filter that improves taste and raises PH. My top picks are the Wellsys and ChungHo in that order.
Whole House Water Softeners.
Water softeners are truly an amazing thing. They remove almost all dissolved solids in water from minimal amounts of iron, manganese, hardness, and even trace amounts of lead. They make the water great for bathing and keep water heaters free of deposits. The drawback is they add trace amounts of sodium to water and can be hard on septic systems. I have one in my home and honestly love how nice the water is. Rather than recommend a brand here I will recommend the type of valve at the top of the unit. My top valve picks are the Fleck Valve and Autotroll as these seem to work a long time even on difficult water.
Whole House PH Correction Filters
Many houses have low PH and for obvious reasons, this can be a big problem. The filters used to correct this are calcium filters also called neutralizing tanks or injection systems. The calcium filter washes the water through Calcium Bicarbonate and that raises the PH. The drawback is it is only effective to a PH of 6.0 or higher. For PH lower than 6.0 they offer an injection system that injects Sodium Hydroxide right into the water as it enters the house. The drawback to both of these systems is maintenance. Either Calcium needs to be added once per year for the calcium filter, or in the case of the injection system, a mixture of Sodium Hydroxide needs to be mixed and added monthly. My Top picks are the Apex System Neutralizing tanks and Pulse feeder 100 for injection systems.
Whole House Iron and Hydrogen Sulfide Gas Filters
These filters work well either using Potassium Permanganate or air to oxidize the water. The iron in the water oxidizes to allow the filter to capture it and Hydrogen sulfide gas is also removed. The drawback with these filters is one Potassium Permanganate is poisonous and both systems require a high PH to work. I have rarely found a high PH in water with high iron and or Hydrogen Sulfide gas. For those reasons I do not have any system I would recommend using these systems.
Volatile Organic Chemical Filters
There are many VOCs that can find their way into drinking water but the most common is oil. These systems use two tanks set in line and filled with Carbon. The carbon absorbs the VOC like a sponge and needs to be removed periodically. A test tap is installed between the two so when the first tank is exhausted it will show a positive VOC. The first tank is removed and cleaned out and the second is moved into the front. The only national chain that I know of that handles this complex system is Culligan.
High Iron, Manganese, Hydrogen Sulfide Gas and Low PH Systems
This system is the king of all systems and can solve 99% of people’s water problems. It utilizes an injector to inject Chlorine and or Sodium Hydroxide into the water as it enters the house. Water then enters a large holding tank with an automatic drain to wash the particulates to drain. The iron and Manganese sink to the bottom of the tank and are washed to drain. Because of the chorine, the Hydrogen sulfide gas is also removed. Finally is there is a low PH, Sodium Hydroxide can be added with the chlorine to solve that problem. Last, the water goes through a carbon filter to remove the chlorine, leftover Iron, and manganese. The carbon filter washes every few days to stay clean. This system is expensive and requires you to fill it each and every month, but the water quality is great.
As I said at the onset there are many types of water filters on the market and each one deals with its specific problems. I would strongly recommend doing research on your various problem before making an investment in any system and know the pros and cons. So there you have it.
