Frequently Asked Questions

How do I know if my water needs to be filtered?

Your public water authority does the best it can to provide you with potable water. However, water passing through a series of pipes to reach your home may contain sediment. Therefore, a sediment reduction filter is advisable on the incoming water line. Our whole house filtration systems help protect washers and seals from premature wear, help prevent aerators and valves from plugging, and help keep your water heater from collecting excessive sediment.

Additionally, if you do not care for the taste of your home's tap water, a drinking water filtration system can help make a difference.

If you are concerned about specific contaminants, you can read city water reports under the "Your Water" tab. You can also search the Environmental Protection Agency's Safe Drinking Water Information System Database at www.epa.gov/enviro/html/sdwis/sdwis_ov.html.

What substances can be reduced by 3M water filtration products?

Our products vary in respect to ratings for contaminant reduction; among our line of offerings are products that reduce chlorine taste and odor, trihalomethane (TTHM), lead, sediment, cysts, arsenic, barium, cadmium, chromium (hex), chromium (tri), copper, fluoride, radium, selenium, turbidity, total dissolved solids (TDS), mercury, asbestos, chloramine, MTBE, and volatile organic compounds (VOCs).

I'm interested in a whole house filtration system, how do I know what size system to choose?

For a home with 1-2 bathrooms, the 3M™ Whole House Filtration System for Well or City Water is appropriate. A home that has 3-4 bathrooms will probably require a larger capacity sediment filter such as the 3M™ Advanced Whole House System for either Well or City Water.

How does the capacity of a 3M drinking water system compare to other alternative products such as bottled water, pitcher filtration systems and end of faucet filtration systems?

Drop for drop, a 3M drinking water system is the smarter choice. Each product's capacity varies, but the 3M™ Full Flow Drinking Water System has a capacity equivalent to 45,443 16.9oz bottles of water, 150 pitcher filters, and 60 faucet filters.
