The 3 Best Aquasana Water Softeners - Our 2018 Product Reviews
When it comes to water softening, Aquasana have it sewn up. Never mind salt, Nucleation Assisted Crystallization (NAC to its friends) is the way to go. Not so much a single device, think of Aquasana water filters as a range of products designed to work together as part of a veritable smorgasbord of water treatment products. You just select the elements that deal with the water issues in your given area.
Designed to protect aspects of the home that come into contact with water, Aquasana water softeners and filters make light work of getting rid of unpleasant minerals and chemicals that you’d prefer not to be there without the need for salt or electricity. Simply purchase them, install them into your plumbing, and let it work.
Aquasana Whole House Filters work with four technologies that pimp up the quality of water available to you at home. (Check out the difference between softeners and filters here)
Why Use an Aquasana Water Softener?
There are a few reasons why Aquasana has such a large repeat customer base, and here's a few of them:
1. Salt Free Softening
Never mind lugging bags of salt around and waiting for water while your softener regenerates like a long lost Time Lord (That’s a Dr Who reference if you didn’t know). Nucleation Assisted Crystallization reduces calcium scaling by an impressive 99.6% so it is especially effective in hard water areas.
Not only do you avoid salt refills, there are also no running costs as there is no electricity or additional water required.
2. Sediment Filters
Yes, it may look clean and clear but your water supply can often carry a selection of unwanted nasties including sludge and sediment from older pipes beyond your home.
Aquasana filters make light work of this in the first stage of their process. Your water is passed across a sediment pre-filter that will ensure your household plumbing and appliances don’t come into contact with rust and other debris from external plumbing pipes.
3. Chemical Filters
Based on a mix of copper and zinc and finely crushed mineral stone, these chemical filters will clean your water at a rate of seven gallons per minute.
Your water then passes across active carbon filters that effectively remove herbicides, pesticides, and any other distinctly undesirable elements to leave clear water that won’t harm you, your pipes, or your appliances.
4. Ultra Violet Filtration
Despite all this filtration and cleaning, bacteria such as E. coli, cryptosporidium and giardia can still be carried in your water supply. The 'Aquasana Sterilight' filter uses ultra violet light to ensure that bacteria are killed before the water passes into your home.
