  • Clean, Great Tasting Water From Every Tap In Your Home - Removes 97% of chlorine and reduces harmful contaminants like lead, mercury, herbicides, pesticides, VOCs, and more

The first Aquasana product on this list, the Aquasana Premium Rhino Whole House Water Filter gives you healthy, clean, great-tasting water from every tap in your home. This filter is able to remove up to 97% of the chlorine in regular tap water. It is also able to reduce pesticides, herbicides, rust, silt, sediment, cysts, water-soluble metals, industrial solvents VOCs (volatile organic compounds), and other harmful water contaminants in your home for 10 years or for one million gallons.

This is a whole water system that can provide you clean, healthier water from your kitchen sink, to your bathroom sink, to your shower. This system will come with the Aquasana filtration tank, fittings for a .75-inch pipe, brass fittings, 20-inch pre-filter, bend supports, brass fittings, and shut-off valves.

It is also covered by a 180-day limited product warranty.

Reviewers report that installing this whole house system can be tricky if you do not have carpentry and plumbing skills, as the accompanying instructions can be difficult to follow if you are not well versed in these fields. It is likely that you will have to get help from a professional plumber in order to get this system up and running in your home. Some reviewers have also reported that there can be a drop in water pressure when you use this system, however, they say that this drop in pressure usually does not cause a bothersome water flow.

  • Instantly Transform Ordinary Tap Water Into Clean, Extraordinary Water - Removes up to 99% of 77 contaminants while leaving healthy minerals so you can drink with confidence. This system will NOT...

The Aquasana AQ-5300+.55 3-Stage Max Flow Under Sink Water Filter System with Faucet is yet another fantastic system by Aquasana. This water filtration system removes up to 99% of 77 contaminants and pollutants while leaving healthy minerals behind. This system will, however, not reduce Total Dissolved Solids (TDS). Total dissolved solids is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular suspended form.

Total Dissolved Solids can be copper, cadmium, nitrate,  calcium, arsenic magnesium, potassium, chlorides, chloramines, sulfates, lead, bacteria, viruses, plankton, and other microorganisms. They enter your water supplies through agricultural runoff, carbonate deposits, industrial wastewater, mineral springs, plumbing pipes and hardware, road de-icing salts, salt deposits, seawater intrusions, sewage, stormwater, urban runoff, and water treatment chemicals. While elevated TDS levels are not really necessarily bad for you, they can make your water taste bitter, salty, or brackish.

They can also cause hard water, scale formation, and staining, all of which can shorten the lifespan of your pipes and appliances. This can be fixed with the help of a water softener and descaler since soft water has less corrosive elements. This system boasts a very high flow rate by powering through a half-gallon of water every minute. Water pressure is generally faster with this system than with traditional drip filters.

This Aquasana product is also the most economical filter on the market at less than 10 cents per gallon filtered. It lasts for 6 months or 800 gallons before you are required to get a replacement filter. When you do need to replace it, the replacement process is easy and quick, without the need to disconnect hoses or water lines. You can also install this product yourself, as it comes to your house with all parts required and an easy to follow installation guide.

 

Features of the Aquasana AQ-5300+.55 3-Stage Max Flow Under Sink Water Filter System with Faucet:

  • Removes up to 99% of 77 contaminants 
  • Will not reduce TDS
  • A high flow rate of half-gallon every minute
  • 10 cents per gallon
  • Lasts for 6 months or 800 gallons

  • Healthier Skin, Hair & Air - Reduced harmful chemicals means more moisturized skin, healthy shiny hair, and less chlorine in your shower steam

The Aquasana AQ-4100 Deluxe Shower Water Filter System with Adjustable Showerhead is specifically designed to make sure you shower with the best, cleanest water possible. This means healthier skin and hair since this water filtration system removes up to 91 percent of the chlorine usually added to municipal water. Anyone who has seen their hair health deteriorate during summer from going to public or private pools knows exactly how much chlorine can be detrimental to your hair health.

The chlorine taste in the water is also not very good, and getting rid of it might help your family drink more water. This unit’s coconut shell carbon filter media will remove harsh chemicals such as chlorine, pesticides, hydrogen sulfide, lead, and other volatile organic compounds, and its KDF 55 filter media made from both copper and zinc can further reduce the chemical content while enhancing the water’s pH. The carbon filtration process can be especially beneficial for your health.

Some reviewers report that the first bit of the water may come out black as the filter cycles out the carbon. However, the health benefits of showering with clean water can become insurmountable to this small inconvenience.

What Are The Benefits Of A Water Filter?

A house water filter system can range from anywhere to mood-lifting additions to your home to life-saving tools for your family. Everyone understands how important water is for your life and your health, and something as important as water deserves to be treated as such. If you are still not convinced, here is a list of the vast advantages to having a water filter installed in your home:

  • Cheaper than buying water bottles
  • More eco-friendly than buying water bottles (plastic)
  • Removes water impurities and dangerous contaminants such as chlorine, disinfection byproducts, and heavy metals such as mercury, lead, and arsenic
  • Ensures that important minerals such as magnesium, fluoride, calcium, and zinc are retained, which protect you from toxins
  • Your water will taste better
  • Your water will smell better
  • It will help skin hydration, nutrient absorption, weight loss, detoxification, digestion, and a reduction in the risk of cancer as well as support the immune system and mental health function
  • Durable
  • Portable
  • Low maintenance

You might also want to look into microns. Micron levels in water filtration are usually between .5 and 5 microns. For example, if bacteria in your water are 1 micron and you have a filtration system with a micron level of 1; it will be able to filter out that bacteria (as well as anything larger than 1). This can be an important element in choosing your water filter, so keep yourself informed.

Water filtration has been around for a long time and has saved countless lives. Although nowadays we get to enjoy a higher standard of living and consequently, a higher standard for our drinking water, there are still people who would rather improve their water quality, either out of need (maybe you get well water to deal with your household’s water needs, which is always less regulated) or out of a will for the betterment of their family’s life. For even cleaner and better water, you can also get a water purifier, which will remove viruses from your water.

 

Final Thoughts

There are multiple businesses around the US that deal with clean, healthier water because they understand that this is an important thing to invest in. Aquasana has been at it for decades, and they know what they are doing.

They have water filters, water softeners, water purifiers, and every other type of system to help you bring better water to your family. Clean water can help you be better hydrated, it can boost your immune system, your weight loss, your mental health function.

Just to reiterate in case you missed it – water is life. It is the single most important thing you can do for your physical and mental health and drinking bad or unclean water can leave long-lasting effects that you might not even be aware of. So if you have a chance to improve the quality of the water in your home, why not go and give it a try?
