Whole house filter systems remove harmful contaminants from all the water entering your home, from your kitchen sink to your shower, so you and your family can enjoy healthy, contaminant-free drinking and bathing. They can also improve the quality of your laundry, cleaning, and cooking, and protect your plumbing and water-using appliances.

Choosing the right system starts with water testing, custom whole house filter systems her DIY or through a lab. Once you know what contaminants are present in your water, you can shop confidently for filters that target those specific contaminants. The biggest drawback of a whole house filter is the initial cost, but this is often offset by bottled water savings and a reduction in plastic waste.

As you research your options, pay attention to the warranty and return policy of each filter. You’ll want to make sure you have an iron-clad warranty and a return policy that allows you to test the product before making a final purchase. Your time is too valuable to buy something that winds up breaking down in a few years. The best warranty I’ve found for a whole house filtration system is offered by SpringWell, for their CF1 model, which features a combination of long-lasting sediment pre-filters and catalytic carbon coconut shell filters. This helps the filter remove more contaminants than a single carbon or KDF filter alone, and it is significantly less expensive to own over the long term compared with cartridge-based options like Pro Aqua and GE.
