How to Choose Carbon Water Filter for your Home

Here is your comprehensive buying guide on carbon water filters. Carbon water filters as a whole are a very trusted and reliable form of water filtration, especially for homes and drinking water. In addition to the product recommendations above, here are some considerations and details that could affect your purchase of a carbon water filter.

One thing to note is that carbon water filters do not soften water so if you have hard water or well water, you may need to have a water softener in addition to a water filter. Hard water can significantly reduce the life of a carbon block filter and could cause maintenance costs to increase.

Whole House Or Countertop

First, you will need to decide if you want a whole house or countertop water filter. Whole house water filters will filter any water coming into your home including shower water, sink water, water used by your washer and dishwasher, and drinking water.

Countertop water filters will only filter the water from the faucet it is directly hooked up to. If you rent or only drink primarily from one location, countertop water filters are a great, budget-friendly option to get clean water.

Percentage Of Removal

Every carbon block filter does not remove the exact same amount of contaminants. Additionally, most carbon block filters are coupled with other forms of filtration such as reverse osmosis or a sediment filter.

It is important to look at the whole system. If you have fairly clean water and just want to drink or use even cleaner water, a system that simply reduces contaminants is likely good. But, if you truly have contaminated water with heavy metals present or high levels of chlorine or pesticides, it might be necessary to look at a higher-quality system that truly removes almost all of the contaminants.

Price

Price can be a huge factor when looking for a water filtration system for your home. Luckily, you should not have to compromise on the quality of filtration to meet your budget needs. A countertop water filter is almost always a budget-friendly option if you need good drinking water. There are also some reasonably priced whole house water systems but be careful as sometimes cheaper systems need maintenance more often which can quickly add up.

Warranties And Guarantees

If you are purchasing a water filter for the first time and are worried about not liking the system or things going wrong, you can check to see about guarantees or warranties. Some have both. Some filters will come with a 30-day money-back guarantee.

Others might have a warranty that is anywhere from 1 to 10-years long. Knowing if there is a warranty or guarantee can ease your mind about making such a significant purchase.

Maintenance

Maintenance will be required for all filtration systems, likely in the form of replacing filter cartridges.

Most systems make maintenance easy: simply pop out the used cartridge and pop in a new one. But what might differ is how often you need to replace them.

Some systems need to be replaced every 3 or 6 months, while others can last up to a year or even two before needing to be replaced. Purchasing cartridges is an added cost, so be sure to factor how much the system will cost per year in maintenance before making a purchase.

Frequently Asked Question and Answered

How often do I need to replace the filter cartridges?

This depends on the brand of the filter. Be sure to follow the instructions given by the manufacturer.

Do I have to know a lot about plumbing?

There is no plumbing involved in countertop systems. You should have a basic knowledge of tools and plumbing to install whole-house systems.

What happens if I forget to replace the cartridge?

If you forget to replace the cartridge you will likely notice the flow of your water slow down significantly. Additionally, it will no longer be filtering contaminants out of the water to its best capacity.

How much of a contaminant will the filter remove?

Check with the manufacturer site as they are usually very transparent about what is and is not removed or reduced. Each filter is different and may reduce or remove slightly different contaminants.

Conclusion

Throughout this article, you should have acquired some very valuable knowledge with regards to the best carbon water filters and the value they can add to your home.
