ACTIVATED CARBON FILTERS

Come to water filters, we have more than the simple term “Water Filters”.

Actually, we have up to 8 different types of water filters for home uses:

Whole House | Under-Sink | Countertop | Faucet Mount | Showerhead | Dispenser | Pitcher | Fridge

Whole House Water Filter

Whole House Water Filter System

Filtering your water for the whole house is more of a necessity than a choice nowadays if you care about your health.

It’s not only for drinking water but also for showering or washing clothes.

Water with contaminants can leave stains on clothes (especially whites) after a while.

Another way you can tell if your water has contaminants is by lather. If the lather from shampoo or soap disappears fast, your water may have contaminants.

That’s the reason why we have whole house water filter systems.

There are whole house water filters designed for well water. They reduce iron, catch sediment, soften the water, and remove the sulfur smell. They also reduce the levels of bacteria growth, chlorine, pesticides, and herbicides.

A typical whole house water filter system removes 95-97% of VOCs and chlorine. It also removes sediment and other contaminants without wasting water.

You can find some simple whole house water filter system under $100, but a typical system has price about 300$-500$, and a large system has a price 1000$-2000$.

3 best whole house water filter systems:

  1. iSpring WGB21B 2-Stage
  2. Express Water WH300SCKS
  3. Aquasana EQ-1000-AMZN Premium Rhino

Here are our picks for the top 6 best whole house water filter systems for all budgets.

Under-Sink Water Filter

The under-sink variety can filter lots of water.

They deprive you of space from the cupboard underneath the sink, hence, they don’t clutter the counter.

You can use some inline filters for more than one appliance.

For example, you might be able to connect your filtration system to your fridge, water cooler, and kitchen tap.

Under sink inline filters are also an inexpensive option.

Most have quick-connect or push fittings that allow a seamless replacement process. They are also known for their durability.

On the downside, inline water filters are not reusable after the end of their service life. You will have to replace it in full when that time comes. This replacement does not amount to high annual costs, given the durability and low cost of the filter.

Here are our picks for the top 3 best under sink & Inline water filters.

  2. Frizzlife Under Sink

As its name suggests, you mount this type of filter on your kitchen faucet. It’s also called faucet attachment water filter.

The water first passes through a non-woven screen around the filter. This screen traps sediments like dirt and sand.

Next, the water passes through a compressed block of zeolite and carbon. These elements remove chemicals such as chlorine.

Faucet mount filters use a combination of carbon and sediment to remove a wide range of pollutants.

2 most popular brands for faucet mount water filters are PUR and Brita.

PUR is superior to Brita when it comes to getting rid of sediments and chemicals. Only Pur is guaranteed to remove cryptosporidium and giardia from the water.

Water Softener
Water Softener

Water softeners are a type of filter that softens water by removing or neutralizing minerals. These minerals cause scale and make water hard (known as hard water).

The filtration system treats hard water by using ion exchange and salt resins. This process removes magnesium and calcium hardness.
Most of the water softeners are designed for whole-house uses, but there are some specific for under-sink and portable.

There are 2 most popular types of water softeners: salt-base and salt-free.

Using and maintaining a salt-based water softener will cost you a little bit more than most other water filters while one pro of salt-free water softener is low installation and maintenance cost.
