Question 1

How is this different from a traditional salt-based water softener?

Accepted Answer

Our systems are salt-free. Catalytic filtration media alters the structure of calcium and magnesium so they can't form hard scale — no salt bags, no chemicals, no sodium added to your water.

Question 2

Which system is right for my home?

Accepted Answer

It depends on your home size and water usage. The Elite-15 and Classic-10 work for any home size (up to 6 bathrooms), while the Eco-5 suits medium homes with up to 3 bathrooms. A free water evaluation confirms the best fit.

Question 3

Do I need to change filters or add salt?

Accepted Answer

No. All of our systems are cartridge-free and salt-free, with no ongoing filter changes or salt refills required.

Question 4

Why is OWS rated #1 by many review sites and consumers

Accepted Answer

OWS prides themselves on leading and exclusive technology and exceptional customer service, with a no nonsense warranty for up to 15 years.

Question 5

Why is the cost less expensive than most other competitors?

Accepted Answer

OWS prefers more customers and satisfied results so that our customers recommend their friends, saving time and expense from expensive advertising.

Question 6

Why is no under the sink filter needed?

Accepted Answer

With our effective whole home filtration it does what it is designed for, no extra filters or expense is required.

Question 7

If there is no maintenance needed why do you come back every year to check on it?

Accepted Answer

The free visits we offer are for customer satisfaction, we want our customers to know we care and that the OWS system is always working. The investment in service we give is far better than the cost of loosing a customer.

Question 8

What warranty comes with the system?

Accepted Answer

Every system includes a 15-year, non-prorated limited warranty covering parts and labor, plus a free annual inspection.

Question 9

Is the water evaluation really free?

Accepted Answer

Yes — a full water quality test and consultation come with no cost and no obligation.

Question 10

What areas do you serve?

Accepted Answer

We're based in Carlsbad, CA and serve homeowners throughout San Diego County, including Oceanside and surrounding communities.

Question 11

What is a salt-free water softener?

Accepted Answer

A salt-free water softener conditions hard water without adding sodium or chemicals. Instead of stripping out calcium and magnesium with salt, our catalytic media changes the structure of those minerals so they can't form scale — protecting your pipes, appliances, and fixtures while keeping water healthier to drink.

Question 12

What is cartridge-free water filtration?

Accepted Answer

Cartridge-free means there are no filter cartridges to buy, track, or replace. Our systems use long-lasting internal filtration media designed to keep working for years without swap-outs, so you get continuous filtration without the recurring cost and hassle of standard cartridge filters.

Question 13

What is whole house water filtration?

Accepted Answer

Whole house water filtration treats water at the point it enters your home, so every faucet — kitchen, bathroom, laundry, and outdoor spigots — delivers filtered water. That's different from an under-sink or pitcher filter, which only treats water at a single point of use.
