Rated 5 out of 5 by from Product arrived as promised. Easy to install. Filter system including this filter has performed very well. The rust and iron have been removed and the egg like odor of the water is gone as well.

Rated 5 out of 5 by from Great Results! I purchased and installed the EQ-1000 filter a couple weeks ago and have enjoyed good, clean water ever since! I was able to install it myself, which was fairly time consuming, but not too difficult. After waiting a day or two to let the new water get through our pipes, we compared our new purified water to both our old unfiltered water and store bought water, and WOW what a difference! We could immediately taste the difference between the new and old water, and the new water was indistinguishable from the purified store bought water. We are extremely satisfied with the performance of this unit, and would definitely recommend it, provided the filters hold up as long as they say they should.

Rated 5 out of 5 by from Water tastes great! This post filter cartridge unit was for routine replacement. We purchased a whole house unit including the softener over a year ago. Prior to installation, our water had a slight taste and odor similar to algae and white scale built up on fixtures quickly. The units have made a world of difference. The water tastes as good as any bottled water on the market and we no longer have to buy purified water for appliances. We installed a dual system side by side and have no problems with flow rate, even when running the washing machine and showering at the same time. I highly recommend the dual unit if you have reasonably high demand. We temporarily ran with one side turned off and the the difference in water pressure while showering was noticeable - especially if water was being used elsewhere in the house. I also recommend a drip plan underneath to catch water in the event you have a leak at the fitting and during filter maintenance.

Rated 5 out of 5 by from Great All good as usual. I got a leak when I replaced the filter but after reading the instructions I found the missing o-ring on the floor & everything was fine again after I put it back in. How silly of me :)

Rated 5 out of 5 by from Love our Aquasana Whole house Filter We live about 35 miles from town. Our well water comes from the lake we live on but for as long as I can remember my family has never had the water filtered and no one would drink the well water and barely bathed in it. We used Bottled water to drink and the tubs always had hard water stains as well as rust in them. When my wife and I took over the family lake home 4 years ago we bought your Aquasana water system and WOW. The water smelled good clear clean no rust no bad taste you can actually drink it. We love it!!!

User Q & A

Does this post filter compatible with the EQ-1000 whole house filter system?

Asked by: Donna Reese Clean Water
That is an Aquasana Whole House Filter System, so yes, the filter will work, and it is easy to replace. I have that system, also called the Rhino Whole House Water Filter 1,000,000 gallon set. This post-filter replacement cartridge can be used with Rhino Whole House Water Filters that contain a post-filter. The post-filter removes particulates 60 times smaller than the eye can see. This includes insoluble minerals and cysts. The addition of this post-filter is considered a polishing agent and adds a level of protection for your household in the event of an outbreak of cryptosporidium or giardia.

Is this the post filter that is used on the rhino eq 300 whole house filtration system?

Asked by: The Dawg
I am taking a guess based on my brief research that yes it should fit. Eq300 was discontinued and now only 600,000 and 1,000,000 gallons is sold and they both have the same size post filter. Only the pre filter comes in two different sizes. But please call aquasana customer service to confirm. I have a 1,000,000 gallons system.

Does it remove lead and other heavy metals from water?

Asked by: anjh
Our whole home systems are only certified to reduce chlorine, since NSF is limited in the testing they offer for Whole Home systems. We do know that the media used can reduce volatile organic chemicals, herbicides, pesticides and other chemical compounds. We add a pre-filter to help reduce reduces rust, sediment and silt and a .35 micron post filter to remove particulates 60 times smaller than the eye can see.

Is it 50% off the MSRP price? For example, the MSRP price on the post whole house water filter is $29.95, so my price would be $14.98?

Asked by: pook
Aquasana foolishly sent this question to me, a previous customer, but they apparently didn't bother to read it. If they had they would have realized this is a question only they can answer. WAKE UP AQUASANA. Your filters are great but this ... not so much.

What is the length of this post filter

Asked by: Marc
If this is the same filter I have, the length is about 9 3/4 inches. It is designed to fit the standard Aquasana filter cylinder, which is the important thing.
