Home Solutions






Hard Water Buildup
More than just a pain to clean, hard water can cause permanent damage to water using appliances, pipes, faucets, and fixtures. Luckily, there’s an all-natural solution that will protect your home.

Chlorinated Water
Locally, chlorinated water is a common problem for many homeowners. The most efficient, cost-effective way to remove chlorine from your water with a whole home chlorine filter and water treatment system.

Smelly Water
Many homeowners complain of smelly water — and rightly so. Many wells contain sulfur (H₂S) which has many negative health effects. Iron and bacteria can also cause smelly water. The best way to find the source is to test for it and move forward with well water treatment.

Iron Problems
Iron can cause staining in the sink, toilets, tubs and dishwashers and appliances. It can also cause buildup in water heaters, pipes, and other household appliances, causing unnecessary cleaning and making it at times impossible to get rid of the staining.

Features of our quality salt-free water conditioners & filtration
Aqua Otter quality salt-free water conditioner is designed to reduce and remove scale from pipes, water heaters and other appliances, by protecting the home from hard water buildup. Unlike our water softeners that use an ion exchange method by exchanging your magnesium and calcium ion with sodium ion.
As the name suggests, our salt-free water conditioner does not require salt or chemicals to operate. This is a crucial feature for those who are sensitive to salt or chemicals, while keeping the beneficial materials in your water.
Aqua Otter's salt-free water conditioners are compact and easy to install, taking up minimal space in your home. We provide a quality, compact design.
For some of our customers that are concerned about the environmen, our salt free conditioners do not require a sodium backwash, therefore there is no salt or chemicals released back into our natural watershed.
A quality salt-free water softener should be cost effective, offering a balance between affordability and effectiveness. So you and your family can enjoy the benefits of pure, clean water.

PFAS & Your Drinking Water
Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that are widely used in various industries and known to be harmful to human health. Reverse osmosis is an effective method to reduce PFAS in drinking water. This process uses a semi-permeable membrane to remove contaminants, including PFAS, by applying pressure to force water molecules through the membrane while leaving behind pollutants. Reverse osmosis helps ensure safer and cleaner drinking water by significantly reducing the presence of PFAS and other harmful substances. Aqua Otter has options to help reduce the PFAS in your drinking water.
