What is a whole house water filter?

A whole house water filter is a filtration system that treats water where the main water line enters your home, ensuring the water that flows from every faucet, every shower head, and even in your washing machine, is clean and filtered. Whole house water filters are point of entry (POE) filters. They are gateways for your tap water and allow only fresh, filtered water to flow to your faucets and appliances.

Do I need a whole house water filter?

You may need a whole house water filter for a variety of reasons. If your home’s water supply contains a troublesome contaminant or generally poor quality, there is a whole house filtration system that can be the solution. If you are on well water, you may need to remove sediment and disinfect your water. If you are on city water, you may want to rid your water of the smell and taste of chlorine. If you have hard water, you will reap countless benefits by installing a water softener. A whole house filtration system can be designed to remove anything that is troublesome from your water.

What is a whole house scale inhibitor water filter?

A whole house water filter system with a sediment water filter is capable of removing sediments and scale build-up.

Are whole house water filters worth it?

Despite subjecting your household water to treatment before sending it down to your home, a few contaminants still end up in the water. Contaminants like PFOS, PFOA, pharmaceutical runoffs, and pesticides cannot be removed by the processes at the treatment center. This is because only a few treatment centers have the technology and systems required to filter off such contaminants.
Likewise, household water is prone to additional contamination when it is distributed to homes from the treatment centers via aging plumbing structures and old lead pipes. This is where a whole house filter can help.

What causes scaling in my water pipelines?

Scaling occurs when the water has high levels of minerals like calcium carbonate, building upon surfaces. Slight scaling can be considered beneficial because the inside surfaces of metal pipes become coated with harmless minerals that act as a barrier to corrosion.

If I don’t change my AP810 water filter replacement every 6 months, can this damage the system?

It is essential to replace your filter after 6 months or sooner, depending on the filter’s performance or the degree of filtration it has been subjected to. Leaving your filters unchanged will lead to fatigue and adversely affect the filtration process.
