Our whole house systems are tested and proven to reduce the contaminants your family worries about most, including chlorine, chloramines, lead, PFOA/PFOS, cysts, and sediment, depending on the specific system purchased.

Whether you use city or well water, we have a home water filtration system that will fulfill your needs. We offer Rhino®, Rhino® Max Flow, Rhino® Chloramines, and Rhino® Chloramines Max Flow whole house water filter systems for city water, designed to last 1,000,000 gallons and up to 10 years. We also offer our premium solution, the OptimH2O®, which is tested and certified to reduce lead, PFAS and cysts, and also tackles chlorine and chloramines. Our Rhino® Well Water with UV whole house water filter system is designed to filter private well water, and lasts for 5 years.

How Our Rhino® Whole House Water Filters Work

To maximize the performance of our whole house systems, we use multiple stages of filtration. Here's how our whole house filters remove contaminants:

  • Sediment Pre-Filter: The sediment pre-filter catches rust, dirt, debris, and silt that may be present in your water. Removing these contaminants improves the quality of your water and helps protect the filtration system from clogging.
  • Activated Carbon: The activated carbon media reduces chlorine.
  • Copper-Zinc (KDF) Media: Aids in the reduction of chlorine, extends the life of your system, and inhibits bacteria and algae growth.
  • Post-Filter: The post-filter reduces any remaining sediment and organic particles.

Whole House Water Filtration System Benefits

Whole house water filters are ideal if you want filtered water throughout your home, including for showers, bathroom sinks, and running appliances like your washing machine and dishwasher. Even if you only want filtered water from the sinks in your home, a whole house system can be cost effective and time efficient versus purchasing several under sink or countertop filters that need to be installed and maintained.

Here are key benefits of an Aquasana whole home water filter system:

  • Reduce contaminants in your water
  • Get healthier skin and hair
  • Improve the flavor and quality of your food and drinks
  • Provide healthier water for your pets and plants
  • Enjoy brighter, longer-lasting clothes by removing chlorine
  • Breathe easier by removing chemicals that evaporate in steam

Upgrade Your Whole House Water Filtration System

Beyond the base model, our whole house water filtration systems can also be customized with the following optional upgrades:

  • Salt-Free Water Conditioner: Prevents minerals from binding and forming scale buildup, which can damage pipes, appliances, and negatively affect the quality of your water.
  • UV Filter: Uses ultraviolet light to sterilize 99.99% of viruses and bacteria and 99% of chlorine-resistant cysts.
  • Pro-Grade Bypass Kit: Includes upgraded brass fittings and a bypass valve that makes your home water filtration system easier to install and maintain, a larger Pre-Filter, and a Post-Filter that catches any remaining sediment or carbon fines that may have passed through filtration.
  • Low Maintenance Pre-Filter: Upgraded pre-filter that lasts 3X long as the standard Pre-Filter, meaning fewer replacements.

Choosing a water filtration system for your home is an important decision to make for you and your family. If you have questions about our whole house water filters including features, installation, returns, or anything else, call us at 866-662-.

What is a Whole House Water Filter?

A whole house filter connects to the main water line entering your house so that all of the water dispensers in your house – faucets, toilets, showers, baths, kitchen, laundry – dispense treated water. Typically the whole house water filter is connected to the main water line before it splits into the hot water heater.

Note: Customers wishing to purify the water to their garden and sprinkler systems may find this to be a bit more challenging as the main water line coming off the city system often splits off into a “house” water line and a “yard” water line in the house’s foundation slab or at the street level before the house. Consult your home’s blueprint or city water utility for further details.

What type of Whole House Water Filter do I need?

This will depend on what types of contaminants are in your water. First, determine what you need to remove from the water. If you are on a municipal city water supply, then the typical contaminants of concern are chlorine (or chloramines) and chemicals, sediment, and hardness minerals. Upon request, most municipal water utilities will provide you with a water analysis.

The types of contaminants typically found in a Private well water supply are sediment, iron and hardness minerals, but can vary from nuisance contaminants to toxic or damaging. If you have a private well, please send us a copy of your most recent water analysis or get your well water tested so we can make a recommendation based upon the contaminants that are actually in your well water.

Water Softening vs. Water Filtration

Water softeners remove hardness minerals specifically, whereas water filters are designed to remove a broader range of contaminants. However they can be used together.

Common Types of Contaminants

  • Sediment – typically refers to visible particles in the water, which need to be mechanically strained out such as dirt, dust, rust, and sand. Water supplies with high amounts of sediment should consider multiple stages of sediment filtration, with the stages gradually becoming finer. Reusable filters should also be strongly considered. Water supplies with less sediment can use disposable, finer filters.
  • Chemicals – most chemical contaminants can be removed using carbon filtration. The most common chemical disinfectant found in municipal city water supplies is chlorine, which can be removed with a carbon filter.
  • Iron – there are two types of iron found in water supplies, ferrous (aka dissolved or clear water iron) and ferric (aka rust or red water iron). Red water iron and rust particles can be removed with a sediment filter, whereas clear water iron can be removed via oxidation or ion exchange. Factors affecting the life of an oxidizing filter are pH and the presence of Hydrogen Sulfide.

Selecting a Whole House Water Filter

Below are a few of the things to consider and look for as you select a whole house water filter:

  • Flow rate – measured in gallons per minute (GPM), flow rate determines the amount of water available to run your shower, toilet, hot water heater, dishwasher, etc. When calculating your requirements look at the demand ratings printed on your appliances and toilet. Typical showerheads flow 2.5 to 5 GPM, toilet 5 GPM, dishwasher 3 GPM. Depending on the size of your house and family your water flow rate requirements may range from 15 - 40 GPM. A whole house filter system with a flow rate less than 10gpm is unacceptable for maintaining uninterrupted, comfortable water pressure during peak use.
  • Filter size – the larger the filter the longer the service interval, and the more water it will flow and with greater pressure. However, the port size has a greater impact on GPM and pressure. The ideal filter size for most homes is 4.5” x 20”, however, large homes may require a second unit in parallel.
  • Filter life – sediment filter life will vary depending on the sediment quantity and quality. Good quality whole house 4.5” x 20” carbon filter cartridges will last 100,000 – 150,000 gallons in normal municipal water supplies. Stand-alone carbon filters with carbon beds, as opposed to carbon filter cartridges, will last much longer ONLY if they have a backwashing valve and a regular back wash cycle.
  • Port size – the ideal port size on a whole house water filter is 1”. Even if the home uses ¾” piping, using a 1” ported system will not create any bottlenecks when fitted onto the ¾” pipe. Whole house water filter systems with 1” ports and 4.5” x 20” filter carry more than enough water so that pressure drops are virtually non-existent.
