Point-of-use water filtration is water treatment to improve water quality for drinking, bathing, washing, irrigation, etc. at the point of consumption. Below are the most common types of point-of-use filters:
- Faucet Filters
Intended to attach to a faucet. They use a granular activated carbon (GAC) or microporous filter that catches contaminants as water flows from the faucet.
Advantages: Low-cost, portable, easy installation, can be used in rental homes.
Disadvantages: Slow water flow, need filter for each faucet, replacing filters can get expensive over time
- Countertop water filters
Use a hose to your water faucet and sit on your countertop (as their name suggests). They generally have a storage tank, and use a couple of filtration processes to remove up to 99.9% of the impurities in tap water. These filters use activated carbon filter and a reverse osmosis filter.
Advantages: Easy installation, low-cost, can be used in rental homes, removes up to 99.9% of impurities
Disadvantages: Slow, limited capacity
Integrated right with your plumbing. Professional installation may be required to do this. These filters may use any combination of activated carbon filtering, reverse osmosis, and ionization to remove contaminants and soften your water.
Advantages: Large storage tank, easy maintenance, installed out of sight
Disadvantages: More expensive, may require professional installation, may not be acceptable in rental housing
