How long does the EQ-300 whole house water filter system last?
The EQ-300 unit is certified for a 300,000 gallon capacity at 7 gpm, the highest certified capacity of any whole house water filter system. A family of 4-5 people uses around 100,000 gallons of water per year. According to this calculation, the main filter unit should be replaced every three years (EQ-300R); no plumber needed. The sediment pre-filter (EQ-304) should be replaced every 3-4 months.

What media is in the top unit of the EQ-300?
KDF-55 is a copper-zinc alloy filter media, specifically designed to remove chlorine, heavy metals, and microorganisms from drinking water.

What media are in the bottom unit?
Bituminous carbon and coconut shell carbon.

How much time is involved in the installation of the whole house water filter?
Typical installation is 1-2 hours when done by a licensed plumber and costs about $200 to $250. Installation by a licensed plumber is required for warranty qualification.

What is the size of the whole house unit?

Whole House Water Filter Benefits

What are the benefits of whole house filtration?
By filtering all of the water that enters your home, you not only greatly enhance the healthfulness of your household water, but you also dramatically improve your indoor air quality. According to the Environmental Protection Agency (EPA), “Every home in North America has an elevated level of chloroform gas present due to the vaporization of chlorine... from tap and shower water." Chlorine vapors are a suspected cause and irritant of respiratory problems such as asthma, bronchitis, and allergies. Filtered water will improve every aspect of your family’s health.

Does the whole house filter system have any benefits for laundry and/or dishwashing?
The EQ-300 will remove chlorine that may be embedded in clothing when unfiltered water is used in the washing machine. Also, colors will last longer and look newer with the chlorine removed. The dishwasher releases more chloroform into the household indoor air than any other source besides the shower. By removing chlorine, EQ-300 prevents this toxic gas from being released. Filtered water in the dishwasher also reduces film or soap scum on dishes. For both laundry and dishwashing, filtered water reduces the amount of detergent you need to use in each cycle.

Contaminant Removal

What contaminants does the EQ-300 remove?
The EQ-300 will:
1) Remove chlorine, lead (lead may be re-introduced by the house).
2) Remove sediment, particulate matter down to 5 microns.
3) Alkalize drinking water, raising the pH to about 7.5.
Rhino EQ-300 has been performance tested by Underwriters Laboratories for chlorine, bad taste and odor reduction.
UL certificate is available on the product page.
The remaining requirements for UL listing, which include plant inspections, literature review and QC manuals approval are currently in process and should be completed very soon.

I have a well. Do you have a system that is designed for well water?
The EQ-300-85 is the version of the EQ-300 specifically designed for well water treatment.

Water Treatment Comparisons

Are drinking water and shower filter units still necessary with a whole house filter?
The shower system is not needed, as the shower filter and whole house filter remove the same contaminants. However, we still recommend the use of the drinking water filter because it removes additional contaminants (such as Giardia and Cryptosporidium) that the whole house filter does not remove. In addition, the drinking water filter will remove lead and other contaminants that are introduced from the home’s plumbing after water goes through the whole house filter.

Does the EQ-300 soften the water?
The EQ-300 will soften hard water a moderate amount, however, if you have very hard water, you may install a water softener to work in conjuction with a whole house water filter without any problems. In most cases, however, we find that there is no longer a need for a water softener after installation of the Rhino EQ-300.

What are the differences between whole house units and softeners?
Softeners use salt to push minerals like iron and calcium salts out of the water, similar to the way insulin pushes sugar out of blood. The whole house water filter is designed to remove chemicals and heavy metals, while retaining good, healthy minerals. The EQ-300 will reduce calcium and iron down to 5 microns with mechanical filtration.

Are whole house systems (P.O.E.- point-of-entry) better than countertop filters (P.O.U.- point-of-use)?
P.O.U. systems are by far the best way to ensure the highest quality water since many water-borne contaminants come from the plumbing in your house, especially lead and vinyl chloride from the piping. By filtering water at the point-of-use, you remove contaminants just prior to consumption, eliminating the chance of recontamination. Point-of-entry systems are very beneficial in that they provide filtered water to all baths and showers as well as any other water appliances. When you filter all of the water entering your home, you improve not only the healthfulness of the water, but the indoor air quality, as well. Point-of-entry filtration results in the removal of chlorine and other chemicals that vaporize and contaminate the indoor air.
