"Simply PUR was a pleasure to work with from start to finish. They were personable and provided us with a lot of information and answered all of our questions. The installation process went smooth and they came back to check our water filtration systems and retested my water. They were honest and sincere and most importantly very reliable and professional the whole way through. Its always a pleasure dealing with Simply PUR. I highly recommend using this company and will continue to refer my friends and family to use them."

"Jose and his team were super professional and very knowledgeable. Not to mention honest. Needed my whole house filter changed and ended up adding on a purified water system for drinking. The whole process was seamless. I would definitely recommend them to anyone looking for an honest and reliable company."

"The receptionist was courteous and personable when I called. The workers arrived promptly. They were professional and knowledgeable. They completed the work efficiently and promptly. I have used filtered water for over ten years. This was the first time I used this company and their prices were entirely reasonable. I have a water tester. And the new water filtering system they installed passed the test for excellent water filtration."

Water Softeners FAQs, answered by experts

Soft water is better for your hair. The minerals in hard water can dry out hair, make it brittle, and leave a film on the hair and scalp that may cause irritation. Hard water also doesn't rinse out shampoo and conditioner effectively, which can lead to product buildup that makes hair look dull and limp. You may also find you need to use more shampoo to get a good lather in hard water.

You can install a water softener system by turning off the water supply, draining the water, and then connecting your device to the waterline. Next, you’ll fill your tank with the recommended amount of salt or brine (whichever your unit calls for; be sure to read the instructions). Turn the water supply on and check for leaks. You can opt to let your water run for a few minutes, then test it using strips. 

The process of inspecting your water softener system is similar.

Some shower water softeners are effective, but this isn’t always the case. Most shower filters only filter out chlorine, not hard minerals like calcium. Other shower filters can't handle the demand in homes with very hard water. It's also important to change the filters on your shower filters. Failure to regularly swap out old filters will make the filter ineffective over time. 

Generally, it is safe to bathe in yellow water, as the color is often caused by iron, tannins, or rust, which won't harm your skin. Soap will still clean you effectively, though the water might leave stains. However, if the water has an unusual smell or you suspect contamination, avoid bathing and contact a plumber for an inspection. A professional can also help if you find bathing in yellow water problematic and want to determine how to get your water clear again.

You can decide whether you need a water softener or water filter based on how your bathing or laundry experience is. If you notice issues like limescale buildup, dry skin, or stains on dishes—all telltale signs of hard water—you'd likely benefit from a water softener. However, if your main concern is over chemicals or bacteria in your tap water filter, and not just comfort, a filter is a better option.
