Water Filtration Systems Types


1. Whole House Water Filtration System (See Our Detailed Review)

⇑ Back to table of contents
Whole house filters usually work well for small and sediment particles, the charcoal filters improve the taste of water. But it isn’t full water treatment usually. With a water softener in hard water regions, the system gives you soft, cleaned from iron and chlorine water for showering and dishwashing. It will also protect your water appliances, such as heaters, plumbing, etc.

A whole house water filtration system generally includes one to three (less often – up to five) filters, working in series. The first stage is filtering out insoluble particles, sediment, and dirt. For sediment reduction purposes there are wound string, spun polypropylene cartridge, or pleated polypropylene cartridges available with a variety of micron numbers. The smaller the filter micron number the finer particles it will filter. The human hair diameter is about 50-90 microns. Usual micron number is 1-5 microns, 10 and up micron filters are used for larger sediment.

Virtually all sediment filters follow the radial flow pattern, water flows into the inner core through the walls of the cartridge. Graded filter cartridges have several layers with gradually decreasing micron number.

The second and other filtering elements remove heavy metals like mercury, copper, lead, iron, manganese, etc. Сarbon filters improve the odor and taste of the water, are good at removing chlorine and chloramines. General chemical reduction filters use specialty activated carbons designed especially for chloramine reduction or with metals removal resin for lead and other heavy metal reduction. Arsenic, fluoride and nitrate reduction filter stages use activated alumina cartridges.

Larger size filters mean less pressure drop, water faster pass over them, and you don’t need to change cartridges very often. So, bigger filters cost a little more but are more productive and last longer than the average water filter.

The 3-stage systems are an effective solution for both well and municipal water supplies and can provide clean water for a large home. One stage and 2-stage models work well for city water supplies.

2. Home Water Filtration System for Drinking Water

Usually, we don’t need a perfect water filtering for the whole home. Preliminary water purification by whole house water filtration system and using high-quality (but less productive and therefore cheaper) drinking water filter is a cost-effective and safe decision.

We will consider here universal filters, similar to those discussed above, but used for additional drinking water purification. Under sink drinking water filters guaranteeing to remove taste, chemicals, and odors. You will have clean cooking and drinking water, and for making baby food and ice. This reduces buying bottled water significantly.

Usually, the units are easy to install if you just take your time and follow the instructions. Under sink systems are relatively cheap, provide high flow and keeps in required minerals. The only way to get better-filtered water is to go with a reverse osmosis system.

Take into account, that three and more cartridge units require a lot of space for installation under your sink! The best time to install reverse osmosis water filtration system when you do a kitchen remodel.

2.2 Reverse Osmosis Water Filtration System (Read Our Detailed Review)

Reverse osmosis is a water filtering technology that removes contaminations from drinking water with a semipermeable membrane. To overcome osmotic pressure reverse water filtration systems need an applied pressure. The solute retaine on the pressurized side and the pure water pass to the other side.  Between filtration and reverse osmosis there are key differences. The main removal mechanism in membrane filtration is straining.

Reverse osmosis water filtration systems are one of the most reliable, can be used even to remove salt from seawater. But they cost more, require additional maintenance, and are cost-effective in regions where there are specific issues with local water quality. Reverse osmosis systems also widely used by aquarium enthusiasts, if you feed your icemaker with reverse osmosis purified water, the cubes come out crystal clear. The water great for cleaning, it dries lint- and spot-free.

I would recommend getting reverse osmosis system that uses non-proprietary standard size sediment and carbon filters and membranes. You will be able to replace components even on a branded unit with generic inexpensive parts.

Some comments for a reverse osmosis water filtration system choosing are:

  1. You should install a pressure reducer in a high water pressure area to limit pressure to 50PSI.
  2. If the water is hard and filtering system doesn’t have a built-in softener, you should install one. The filter will last longer.
  3. You only get part of the water, entering a filtration system. The rest is discharged into the wastewater pipes and lost,  that will up your water bill. With a permeate pump, reverse osmosis systems are more efficient and get more life out of the membrane.
  4. The purification is slow, consider a larger storage tank for a large family.
  5. The system could be located below the kitchen sink in a basement.
  6. Reverse osmosis water is more reactive than tap water, use plastic tubing instead of steel ones.
  7. Remineralization filter or a powder (pill) for your water jug to put the magnesium and calcium back in for better drinking.

2.3 Countertop Water Filtration Systems

Counter-top filters are accessible for in between $50 and $300 and are easily set up as a Do it yourself venture. This type of program sits on leading of a countertop and is linked to the water provide or faucet closest to it.

The way they perform is by holding a supply of h2o separate from what arrives from the faucet. That way you can have a supply of clear drinking drinking water but do not want to filter dish washing h2o or cooking drinking water except if you select to. With a countertop filter you also do not shed any of the regular h2o strain you can sometimes drop when using an beneath sink filter and you will not use as several filters as with a faucet mounted unit because there is no need to filter each drop of water that is used.

A high quality countertop filter will use numerous sorts of filter systems to clear the drinking water. This consists of a mixture of absorption filters as properly as particulate filters. You may possibly be able to use a significantly less costly countertop system that only utilizes 1 kind of filter but you actually should have your water examined to choose which filter is the 1 you require the most.

Particulate filters, also identified as micro filters or mechanical filters, get rid of points like sand,some pathogens and bacteria.Although carbon based mostly absorption filters are more valuable to remove chlorine and other things like pesticides. Taking away the chlorine on your own will improve the scent and flavor of your drinking water.

The big disadvantage to a countertop h2o filter system is area. This method requires counter area and for these who have really tiny counter room that can be a problem.

There are numerous advantages to the use of a countertop program, clean consuming drinking water, ease of set up and high ability filters to identify a handful of but if area is an concern for you it might be time to appear into an below sink filter program.

Countertop Water Filtration systems usually are carbon filters with a simplistic design for easy installation, making it possible to set up in minutes with no plumbing required. Remove chlorine and heavy metals, saves minerals that our body does not produce such as magnesium, calcium, sodium and potassium, helps to naturally balance the pH of water.

Countertop water filtration systems have up to five filtration stages combined in one cartridge. The filters install right on top of your counter and can be simply maintained by regularly changing (in models with changeable filtering elements).


3. Cup (Pitcher) Water Filters

In a cup water filter water slowly pours passing through the filter under gravity. Pitchers are simple units, nothing to break. Filters last long taking out some of the chlorine, mercury, copper, zinc, and cadmium from tap water. All you need – change filtering cartridge as stated by the manufacturer. It’s become obvious when you start to smell chlorine in the water. If you drink much or have a large family, replacing filters can get quite expensive and better to think about under sink or countertop filtering system. But in any case, it is less expensive than purchasing bottled water.

Some cup filters have electronic filter indicator, which lets you know when you need to change the filtering element. Pitchers hold about 10 cups of water and filter about 50 gallons (2 months for the average household).
