Learn About Replacement Filters

Water Filters, Replacement Parts & Other Accessories

Clean, pure water is a life-giving necessity. Water filtration systems are designed to help remove contaminants in your water supply; most are undetectable by taste and cannot be seen by the human eye alone. With the latest advancements in filtration technology and accessories, you can enjoy all the health benefits of pure water without worry of heavy metals, harmful pollutants or unwanted bacteria.

In addition to the many full-service water filtration systems, Allergy&Air includes products like replacement ultraviolet bulbs for UV filtration, filters for various stages of filtration—including carbon and sediment—and replacement parts for pitchers and countertop systems. We carry quality products from many household brands, so you can easily find exactly what you’ve been searching for.

Achieve Cleaner, Safer Water with Proper Filtration

If you are a frequent consumer of bottled water, you may be spending much more money than you need. The amount of waste produced by bottled water can seem quite terrifying; did you know, plastic water bottles are one of the largest sources of waste on our planet? A more cost-effective, environmentally friendly solution is to invest in a water filtration system. Whether it’s a filter pitcher or reverse osmosis system, you would save much more money, and we have all the accessories you’d need—at a price that can’t be beat.

The U.S. Environmental Protection Agency is careful about testing public water supplies, but many people with private wells or reservoirs do not have the same strict safety requirements. Also, old houses and buildings with lead pipes can pose health risks. We carry filters that can remove dangerous heavy metals like lead and mercury, in addition to sediment and chemicals such as chloramine. Investing in a water filtration system is a great way to attain peace of mind that your water is safe to drink for you and your family.

To keep any filtration system working properly, it is imperative that you have all the right components. You should always have a stock of replacement filters on hand so you can perform the required maintenance—keeping your system up to date. How effective will your water cooler/filtration system be with expired, overused filters? Our selection of accessories help make sure your water supply remains safe and healthy.

Whether or not your specific system is available on our site, many models work well with a variety of brands and applications; there’s no need to spend unnecessary money on an entirely new system.

Water Filter Accessories You Can Trust

Water is a crucial necessity for everyday survival; your body needs water to function properly and keep you in good health. While all people depend on water, impure drinking water can be very harmful. Proper filter maintenance is important if you want your setup to effectively treat your water.

Ensure your filtration system is operating to its best ability; browse our impressive collection of water filtration accessories and enjoy a steady stream of clean, safe, delicious water.
