What are Whole House Water Filters?

A whole house water filter is a system installed where the main water line enters your house. It helps remove contaminants such as chlorine, lead, iron, sulfur, and other chemicals from your water before it reaches your taps.

Whole house water filters are great for homes with multiple bathrooms or kitchens. You can install one in any room of your home, including the kitchen, bathroom, laundry room, etc.

They work by removing contaminants from the water before it flows through your pipes. Once the water leaves the filter, it goes straight to your taps without passing through any additional plumbing.

Whole house filtration systems are affordable and convenient. They’re easy to install and maintain, and they save you money on bottled water.

How Do Whole House Filters Work?

There are two main types of whole house water filters: those that use activated carbon and those that use ion exchange. Both work well, but activated carbon filters are better at removing chlorine and other disinfectants. Ion exchange filters are better at removing heavy metals and minerals.

Activated carbon water filters are great because they remove many types of contaminants from your drinking water. But sometimes, you may want to add additional filtering capabilities to your whole house water filter. One way to accomplish this is to purchase a whole house water filter that comes with an added silver or KDF filter. These filters will kill off any harmful bacteria and prevent future contamination.

Whole house water filters come in several sizes. Some are small enough to fit under a sink, while others are big enough to cover entire rooms. Whichever size you decide to buy, be sure to pick one that fits your needs.

To find the right whole house water filter for your home, start by checking the specifications of the filter. Look for a rating that indicates how much of a particular pollutant the filter removes. Also, look for a rating that shows how long the filter lasts before needing replacement.

Once you’ve found the right whole house water filter, you should consider adding a silver or KDF filter to it. These filters will kill any bacteria that might enter your home. And since these filters are attached to the whole house water filter, they won’t clog like regular filters.

Why do You Need to Change the Filter?

Changing your water filter every once in a while is a smart move. Not only does it keep your water clean and healthy, but it also makes sure that your whole house water filtration system works properly.

A high-quality water filter will last longer and work more efficiently than low-quality ones. High-quality water filters can last up to 36 months, while others may last just 3 months.

Check to see if your cartridge needs changing before buying new ones. If you notice any problems with your current cartridge, such as weak water flow or unpleasant taste, then it might be time to replace it.

Don’t just think that because your filters don’t seem to be working properly, they’re actually defective. Some filters simply require replacement due to wear and tear.

To find out whether your cartridge needs replacing, check the owner’s manual of your whole house water filer.

What Happens If You Don’t Change Your Filter?

If you don’t change your water filter according to plan, you risk compromising the performance of your other household appliances. Changing your whole house water filter every year or two is important to keep your home safe and healthy.
