The sediment stage one housing is reinforced and transparent allowing you to see how it removes the impurities from your water.

It instills confidence to find a filter that will remove up to 99% of contaminants while adding healthy minerals into your water. What sets this apart from most filters is it only adds calcium which improves the smell and taste of the water, unlike other Alkaline Water.

However, the flow rate isn't that amazing, and it can take some time to fill up. It also takes around 20 gallons of water to flush out the water filter before you can use it and it's best you do so to enjoy high-quality and clear water.

However, users complain it spills water during the fill-up process. The solution is to monitor the process and switch it off once complete. This method also allows you to keep track of your water consumption.

Introducing the Brita Stream Cascade. This water filter with a pitcher has a 12-cup maximum capacity and constantly filters to ensure you don't wait to drink water. It's less than $50 and saves you significant sums of money in bottled water costs.

So, unlike other products in its class, the Brita Cascade is more convenient. It's also lightweight and suitable for seniors. The water also pours at the same rate and prevents spillage when kids tip it over. The electronic indicator is handy and allows you to change the filter at the right time.

The product filters water at a slower rate when the water level is low. Ensure you keep it topped off to maximize the value.

The Buyer's Guide to Choosing Best Water Filter for Apartment

What's the best water filter for an apartment? Well, there are quite a few things to consider before you go shopping.

How to Choose the Best Type of Water Filter

Water filters come in various types. Some are easier to install, and others take less space.

Pitcher Water Filter

The pitcher water filter or water pitcher with filter is one of the most affordable filtration systems on the market. It's excellent at ridding your water of chlorine and often contains minerals to increase the Alkaline levels of your water.

The water pitcher filter is compact, and you can store it in your fridge for some refreshing, tasty, clean water.

Pros
  • Simple setup and requires no installation
  • Great for use at any part of the apartment
Cons
  • Cannot filter significant amounts of water in one go
  • Filter efficiency is not as exceptional as installed water filtration systems

Faucet Water Filter

If you want a water filter that doesn't require an engineering degree to install, the faucet-mounted water filter is an excellent choice. The water filter allows you to switch between unfiltered and filtered water. However, it has a slow flow rate when using the filter and only works for standard filter types.

Pros
  • Simple DIY installation and ideal for renters
  • Affordable
Cons
  • It doesn't fit all faucet types
  • Similar effectiveness with pitcher filters and not as good as other installed systems

Countertop Water Filter

The best thing about countertop water filters is the access to filtered water right from the kitchen sink without altering your plumbing. It's easy to install, and you can take it off the kitchen sink and install it on any standard faucet in your house.

Pros
  • Can provide filtered or unfiltered water
  • Most convenient high flow rate water filter
Cons
  • May look out of place at home
  • It doesn't work for pull-out sprayers

Under Sink Filter

The under-sink filter is excellent for solid flow rate and long service life. These filters eliminate up to 99% of contaminants, ridding your water of lousy color and smell. However, most require a herculean effort to install, and it's better to hire the services of a professional who will most likely use special tools to modify your plumbing area.

Pros
  • High flow rate water filter that is hidden away (under the sink)
  • Limited faucets for drinking filtered water
Cons
  • Requires space and altering kitchen plumbing to install
  • Expensive for a professional install and time-consuming for D.I.Y.

Reverse Osmosis Systems

Reverse osmosis or RO filters remove water impurities in multiple stages. They come in various forms, but one thing they all have in common is the R.O. membrane that eliminates 99% of contaminants from your water.

Pros
  • 99% filtration efficiency
  • Dedicated faucet for drinkable filtered water
Cons
  • Eliminates both bad and good minerals
  • Requires space to install because of the holding tank

Whole House Water Filters

Whole house filtration systems supply the entire house with filtered water. This filter type is the most expensive of the lot and has a high flow rate, ensuring filtered water on demand.

Pros
  • Long service life
  • Often includes water softener
  • Filters all the water entering the apartment
Cons
  • May not filter all contaminants, ensuring additional water filters at the point of use
  • A plumber is an absolute must

Things to Look for in the Best Water Filter for Apartment

Are you having difficulty choosing the best water filter for your apartment? The factors below will help you make your mind.

Purpose

There are many reasons why people use water filters. Some users prefer simple systems to improve the water taste for cooking, making coffee, and drinking. Others want a four or five-stage device to eliminate every single contaminant.

And still, others want something small enough to fit inside the fridge. Whatever your case may be, choose a product that's suitable for your situation.

Filtration Process

Water has various filtration processes, and each type has its benefits and drawbacks. On the list above, you'll find simple pitcher filters that rid your water of heavy metals and T.D.S. with an ultrafiltration membrane.

At the same time, others use UV light treatment together with activated charcoal to eliminate bacteria.

Flow Rate and Filtration Capacity

The flow rate is the gallons per minute (G.P.M.) which is the amount of filtered water you can get from the bathroom or your kitchen tap. Higher flow rates allow you to receive filtered water quicker compared to slow flow rates that keep you waiting.

The filtration capacity signifies how much water the equipment can filter in its lifespan. Some water filters for apartments allow you to change the filter after three to six months. Small water filters often require more frequent replacement.

Installation and Maintenance

Some water filters use push-fit materials, making it a breeze to install, while others require a certified professional not to void the warranty. Additionally, the installation cost, including the price of materials, may eat too deep into your expenses.

I know people who bought water filters and had to throw them away because the parts were too difficult to replace. In some instances, it's more affordable to buy the parts for simple smaller systems compared to complex water filters. Ensure you have adequate information to install and replace the parts for your water filter.

Warranty

A water filter without a warranty is a red flag. You'll be doing yourself a favor to look at other options. Sometimes, these products fail after a specific time. Ensure you can get a refund or a replacement before you buy.

Water Softening

Some water filter products – mainly whole-house systems often include water softeners that reduce water hardness, including the minerals that cause scaling.

Electricity

Electricity is necessary for most water filters. Many water filtration systems fail to work without electricity. For instance, UV Filtration systems require electricity to kill bacteria via ultraviolet radiation. Additionally, RO systems use electricity to power the water pressure through the reverse osmosis membrane. Water filters that use activated carbon don't need electricity.

However, the UV and RO systems that require electricity are better and more efficient at removing contaminants that cause waterborne illnesses. These electricity-powered water filter systems take out the good minerals alongside the harmful pollutants, giving alkaline filters the edge.

Wrapping Up…

Having a water filter in your apartments helps eliminate 99% of the bacteria and contaminants that cause diseases like cancer and lead poisoning, amongst many others.

Instead of settling for the potentially contaminated tap water, invest in one of the water filters for apartments listed above.

Whether you need a compact option or one without a tank to fit the smaller apartment dimensions, you can find a water filter to fit your needs.

However, if you want equipment that combines performance with affordability, we recommend the APEC Reverse Osmosis Water filter for your water consumption needs.

Improve your drinking water quality today and consider one of the apartment water filters above.
