What is a Water Filter

Water plays a very important role in our life. It takes from 50% to 90% of the weight of any living organism and provides the existence of all creatures. Everybody knows that most human diseases are caused by poor-quality water. Hence, getting a pure potable water at home has become a critical issue. With a multitude of water filter brands and purification methods, choosing the right filter may be puzzling. Home water filters come in several types and vary from plain to advanced and complex. Some models filter mechanical impurities and reduce the chlorine content while others catch contaminants and odours as well as microbes and viruses. We are going to review 5 best water filters so you can pick one and enjoy a pleasurable taste of clear water and make your cooking delicious. Even a tiny water filter is able to save hundreds of pounds, and a water filter system will save much more allowing you to get rid of buying plastic water bottles. So, take are of your health and drink pure water only.
As we have mentioned before, dishes will be tastier if cooked in pure water. We recommend considering pressure cookers and slow cookers to make your food even more delicious and get the best of it.

What Features to Compare

Type
Buying a water filter, you should know the quality of the water supplied to your home. Of course, a chemical analysis in a laboratory is the best way to establish the water quality. The water may have visual and gustatory signs can hint at its problems. For example, it may be a feculence, metallic aftertaste and a foreign smell. Once you know the peculiarities of your water, you can decide which water filter you need. Water filters come in pitchers, dispensers, faucet filters, flow filters, and each model is designed for specific pollutants.

Purification method
Most water filters are based on mechanical purification (one or several stages). The water flows through such filters by gravity and this is typical of pitchers and faucet filters. They are the best for purifying the moderately polluted water and for post-treatment. Reverse osmosis systems are more advanced and feature fine membranes that clean water on a molecular level and are able to clean even a severely polluted water.

Filter life
The filter life is an important aspect to consider. The filter performance is the indicator of its efficiency. The majority of filters are able to process about 150 l before it needs to be replaced, while others can do more and save lots of money on buying water in bottles.

Installation
The water filter installation is worth your attention as well. Pitchers and dispensers are easy to accommodate on a kitchen table or on a fridge shelf, while water filter systems should be integrated into a water pipeline. Filters and clean water tanks are usually installed under a kitchen sink. It is more complex but such filter systems are more efficient.

Filtration results
Each water filter has a purification system that allows it to bring a specific filtration result. One category of filters can remove mechanical impurities, chlorine, zinc, copper. Multi-stage filters deliver outstanding results as they remove contaminants, eliminate up to 99% of germs and saturate the water with minerals.

Usability
Each water filter has special features that make it handy. For example, an indicator light will help you replace the filter cartridge on time. A large water tank provides a longer clean water supply. Some water filters have removable bases for space saving and convenient taps for pouring water without lifting the filter or removing it from a fridge.

Ispring RCC7AK

Incredibly Productive and Not As Complex as It Seems

iSpring RCC7AK is a 6-stage water filter system that removes dirt particles, impurities, and even bacteria and viruses. Despite a quite sophisticated design of the unit and its capacious water tank (12 l), it's quite easy to install it under a sink or in a cabinet. The system is able to filter about 280 l per day and features a 360° rotating tap with a ceramic ball valve that proves durability and dependability. We'd like to note that's it's a reverse osmosis system with a mineralisation filter. Having run through the filters and membrane, the water gets mineralised. The mineralizer saturates the water with useful salts and minerals easily assimilated by a human body. The cartridges should be replaced at least once a year, and once a half year in the event of heavy-duty use, while the membrane lasts for 2-3 years. Having installed this iSpring filter, you'll be sure in the water pureness and never regret you've installed it in your place. If you wish to use not a simple filter but an efficient filtering system, make sure to read our review of the water filter systems.

PUR 3-Stage

Stylish Tap Purifier

This PUR water filter is very different from its conventional peers. Unlike standalone models, this filter is attached to the sink tap. The installation of the filter is done with a single click and you'll be able to do it tools-free and without assistance. The carbon cartridge demonstrates great efficiency removing unpleasant chemical smells as well as zinc and copper from water, leaving it totally purified and odour-free. According to manufacturer, the filter can last for about 2-3 months of use due to its 380 l efficient purification capacity. In order not to miss the moment when it's time to change the cartridge, the system has been fitted with an indicator light that glows green when it's operable, yellow when the cartridge is close to being not efficient and red when it's time to replace it. 
The filter looks elegant and will perfectly fit into your kitchen tap. The obvious advantage of this tap purifier is that it delivers purified water the same moment when you open a tap and there's no need to wait at all.
