Aquasana Whole House Water Filter & Softener Reviews

An Aquasana whole house filter is the most comprehensive solution to poor water purity.

A whole house water filter is fitted onto the home’s incoming water supply and treats every drop of water that enters your home at the point of entry.

These systems often need to be installed by a professional, however, they are designed to treat and purify the water in your whole home to ensure that pipes are not overcome with scale, contaminants are removed by contaminant grabbing media, and every tap in your home provides only great quality purified water.

These systems are usually more expensive than point-of-use filters, so it is worth reading up before you buy.

We go into detail below reviewing Aquasana’s best whole home filters.

Post-filters have a longer life and it is advised that these are replaced every 6 months.

The customer care is very familiar with the products that Aquasana in a way that other manufacturers simply can’t compete with.

Main Features & Benefits

Contaminants Filtered:

Aquasana made a wide range of products that can be fitted to best serve the needs of your home. Our reviews cover only a fraction of their full range – an Aquasana water filter can be bought to remove:

  • Sediment
  • Scale-inducing minerals
  • Chlorine and chloramines
  • Lead, Mercury, and other heavy metals
  • Pesticides and herbicides
  • VOCs

A water filter system can remove the majority of chemicals in a water supply, but if you are unsure we always advise you to have your water professionally tested, especially if it is well water or from a borehole.

Flow Rates: 

Put simply, the flow rate is the amount of water that your filtration plant can process at one time.  

Many factors can affect flow rate, including water use elsewhere in your home.

Most water filtration systems are designed to provide a suitable flow rate for their application, however poor water pressure and incorrectly sized filtration systems can cause flow problems.

Filter Micron Size:

The filter micron size describes the “holes” in the filter through which water can flow but contaminants become trapped, preventing them from reaching your taps.

Pre-filters usually have larger micron sizes to capture sediments, while post-filters have smaller micron filters to filter as many particles as possible from the flow.

Generally, smaller micron filters usually require more regular replacement and can cause flow rate issues, while larger micron filters are less effective at removing debris.

Scale Inhibition System:

Scale can cause huge damage to pipework and plumbing systems in the home and is responsible for the deaths of many household appliances!

With the patented SCM technology, Aquasana filters are able to eliminate scale before it reaches your plumbing, giving you peace of mind and saving you from expensive home repairs!

Is Aquasana An American Company?

Yes, Aquasana is made in the USA and it is a great choice for those looking for an easy-to-use water purification system that is designed to last.

Do Aquasana Filters Remove Bacteria?

Their filters are able to remove bacteria from the water, ensuring that your family has clean and safe water to drink.
