Types of Water Filters


Since they are installed at a home’s water source, whole-house water filters are a convenient, “always on” solution for cleaning up your supply. However, they are expensive to install, may require maintenance depending on the model, and may rely on water pressure to get their job done. Because of this, they may fail in emergencies, when we often need our water filters the most. Aqua-Pure is a well-known brand of whole-house filters.


These are essentially a less resource-intensive version of the whole-house filter. Usually installed at the water’s terminus (just below a sink), they treat the water for that sink only. Since they focus on a single sink, are often cheaper than whole-house filtration systems. However, they are also prone to failure during situations when water pressure is lost, for whatever reason. Doulton is a well-known brand in the under-sink space.


There are many sizes and intended uses of gravity filters, from large-group countertop models like the Crown Berkey all the way down to MSR’s personal-use AutoFlow Microfilter. The thing that unites these filters is, as you’d guess, its reliance on gravity to filter water. The benefit of relying on gravity is that it is essentially “no-tech”—gravity doesn’t break down, require maintenance, or need municipal water pressure to filter water. This is very useful in situations where infrastructure is degraded or nonexistent. Other brands include Nikken PiMag, Katadyn, and Doulton.

Emergency / Portable

Though most countertop, gravity, or camping filters can be used in emergencies, many of them are a bit bulky for only occasional use. If you anticipate using a filter primarily in emergency situations involving the loss of water pressure (such as in a natural disaster), it’s worth keeping the size of the filter tank in mind for storage and portability reasons. The Travel Berkey the Katadyn Ceradyn are examples of gravity filters that take tank size into account.

Personal / Camping

Even more so than emergency filters, personal water filters are designed for completely on-the-go filtration. Use cases can range from leisurely camping to serious survivalist needs. The aforementioned MSR line is pitched to these users, as are most Katadyn and Sawyer filters.

Top Water Filter Brands


This Colorado-based company has a passionate fan base and is the countertop water filter leader. The key to their success lies in their filters, the Black Berkeys. Their proprietary filter composition stands in contrast to most competitors, who typically employ a carbon/ceramic composite. While the latter is quite effective, Berkey’s filters stand in a class entirely their own. Models include the Big Berkey, the Travel Berkey, the Royal Berkey, the Berkey Light, the Imperial Berkey, and the Crown Berkey, which differ primarily in size and are geared toward targeting different use intensities. Optional fluoride/arsenic filters and shower filters are available.


Sawyer’s water filters are one of several lines of products designed to provide protection to users in extreme environments, including areas with degraded or nonexistent water infrastructure. Sawyer’s filter construction is proprietary, employing a hollow membrane construction based on kidney dialysis systems. Water filtration products come in a wide array of form factors, including squeeze, water bottle, and gravity filtration. Emphasis is on portability.


Nikken’s PiMag filtration systems employ several filters of differing construction, including ceramic & charcoal, to effectively address a broad array of water contaminants. A unique aspect of Nikken’s technology involves “pi minerals,” which include magnetite, calcium, and silicates, and which results in a slightly alkaline filtered water thought to help counteract the negative effects of our acidic modern diet.


Offering a wide array of water filtration systems, including countertop, under-sink, and whole-house filters, Doulton is a leader in ceramic filtration. Popular products include stainless steel and polypropylene countertop models, instant hot water filters, and boat-specific filtration systems. Rather uniquely, Doulton also specializes in faucets, making installing integrated under-sink filters a breeze.


Katadyn specializes in portability, emphasizing on-the-go use over in-home solutions for water filtration. Product lines include the Ultralight Series, which are purported to be the lightest such systems on the market, the Backcountry Series, which is pitched toward longer single use or two-person uses, and the Endurance Series, pitched for group expeditions. Two of these latter products are the Ceradyn and the Gravidyn, both of which are gravity-based filters perfect for latter-day use.


A 3M brand, Aquapure filters are primarily whole-home systems designed to address a range of concerns. To this end, filters may be pitched to target specific issues such as rotten egg odors or mineral white scaling. Water softeners and ultraviolet treatment systems are also on offer.


Primarily known for higher-end camping gear, MSR’s water filters are understandably created with backpackers in mind. Notable products include the AutoFlow Microfilter, a lightweight (10.5-ounce) personal gravity filter pouch, and the robust MiniWorks EX microfilter, a robust, carbon/ceramic-based filter designed for heavy outdoor and on-the-move use.

Instructions to get the best out of water filtration system

Pre-Purchase Instructions

Before you go to buy a filtration system, do a thorough search on the latest technologies in filtration and what could be the possible side effects of a particular system. Read the reviews of a particular product to get a better idea of it. A water filter system may use RO technology, UF3, or any other technology.  Read how the water is processed in the filter and what ingredients the output is composed of. Make your decision of purchase on a basis of thorough research.

Make a proper space

An under sink filter can easily be adjusted without taking much space. You just have to properly connect it with your sink tap. The storage tank can be placed beside and can be used for different household purposes. Perfectly adjusting the filter system will not make it look bulky in your small kitchen. In fact, your kitchen will look complete with a water filter system in perfect place.

Read the manual

Each water filtration system has different parts such as filters, cartridges, storage tank, connecting tubes, faucet and fittings. Adjusting those parts may require a help of a plumber but using the manual guide provided by every filtration company, you can easily install it yourself. Some filters have wrenches that make it a bit difficult to replace the cartridges every time. Some have push-in technology, which are very easy to install and replace.

Keep a check on replacement periods

Notice the time period of your filter systems regularly and also keep a check on its replacement time. Some filters have no need of replacement for a whole year while some should be changed twice a year. It depends on the material of cartridges and the gallons of water purified by the filter system. This is very important for the efficiency of the filtration system because the impurities extracted by the filter sticks to the walls of the filters’ membrane. This can also clog your system or may reproduce the impurities in water after exceeding the limit.

Stop water wastage

Water wastage is a common problem in all filtration systems. It cannot be avoided; however, instead of wasting that water you can use it for different purposes such as gardening, dishwashing and other household needs except drinking and using it for cooking.

Safety First

Some filters need electricity to run. Water and electricity are far known enemies and thus require special attention. Connect the filter with electric socket but make sure the socket does not have any direct or indirect contact with water. Also if you need to turn on or turn off the purifier, you must not touch it with wet hands. In case of any circuit problem, shut the main switch off and then continue with its settings. A little care can save you and your family from bigger loss.

Storage tank cleaning

Most of the filters have a storage capacity and for this purpose a storage tank is also a part of the system. Make sure the storage tank is washed regularly and do not use 2-3 day old stored water. Prefer drinking freshly purified water.

Live a healthy life

Last but not the least, is that you maintain your health by drinking safe water and saving yourselves and your family from every bad effect of polluted water. A healthy life is a key to successful life.


From these water filter reviews, you can easily evaluate the best water filter for your household needs on the grounds of price, features, quality, certifications, space requirements, ease and warranty periods. Preferences for choosing a water filter may vary but the ultimate requirement is a water filter system which gives you the best quality, safe and pure water for you and your family.
