As housing prices continue to soar out of control and climate change continues to devastate, it's not surprising that many people are looking to solve both problems at the same time.

Please allow 2-4 weeks lead time for this product.
This package offers all of the pre-filtration, pumping, and post-tank filtration elements necessary for smaller rainwater harvesting applications such as tiny houses, mobile homes, RVs, sheds, garages, and more.
The purification unit comes pre-plumbed and pre-wired, requiring only two plumbing connections be made and one electrical connection. This system is all powered by either 12VDC or 110VAC connections, 2 amp max.
Dimensions - 24" Length x 12" Width x 30" Height
Note, picture shown is with 12VDC UV light and junction box. The 110V model will come with a waterproof GFCI outlet for single plug-in use.
The filtration and pump system is not designed for outdoor installation.
Pre-Tank Filtration:
Filtering the water off the roof is essential to giving you the highest quality, healthiest water possible--especially if it is a primary use of water for your application. The WISY Garden Downspout Filter Package will filter out any particles larger than 440 microns and can be mounted in-line with a downspout. Each filter is suited for up to 1,000 square feet of roof area.
Post-Tank Filtration:
Space is at a premium when it comes to small homes, that is why RMS has developed a rainwater filtration system with a minimal footprint and minimal electrical demand. This filtration skid will remove sediment in the water, reduce odors and discoloration, as well as eliminate bacteria in the water by way of the ultraviolet light. We take the guess work out of setting up a filtration system by mounting components and pre-plumbing the filters--all you need to do is plumb into and out of the skid and supply the power.
How much water can I collect?
One of the first things to consider when deciding whether or not a rainwater harvesting system will help meet water demands is your collection potential. An easy calculation to determine your collection potential is below: Yearly Rainfall (inches) X Roof Footprint (square footage) X .62 X .95 = Gallons
Note: When picking out a rainwater tank, do not size it to the total yearly collection potential as you will use water throughout the year. If you need help sizing a tank, please follow the link here.

Sturdy, Easy to Set Up, and Looks Great
Color: Grey, Size: 34" - 3 Panel
I’m really happy with this RANTILA 3-panel room divider. It was simple to set up, stands securely on its own, and gives plenty of privacy. The height is perfect, and the panels look clean and modern in my space. It’s lightweight enough to move around but still feels sturdy. Overall, a great divider that works exactly as I needed.

Not 6 ft
Color: Grey, Size: 34" - 3 Panel
I bought this for filming my auditions. I am 5’4” .The height lists is 6 ft but the fabric only reaches 5’9 1/2 “!
when I must film myself head to toe, the top bars are showing. It’s easy to set up. But when I film I must tilt my camera to keep the top bars out of frame which is not acceptable.

Perfect for what I needed - getting a 2nd one.
Color: Black, Size: 22" - 4 Panel
Putting it together was a BEE-OTCH!! Yes, one of the tubes had the top cap installed at the wrong end (& getting it off required tools), and yes, stretching the fabric to get the screws in was incredibly hard...but am I buying another one? YES! After all is said and done, this is a great room divider. I opted out of installing the paddle feet & it still works perfect. It won't filter light all that great and even though it stands on its own, it can be blown over easily - but for the price? Excellent. If I wanted a heavy duty, thicker, more expensive one, I would've bought one.
The 2nd one is on the way.
Perfect height, no weird smell, nice and light and easy to move around.

WHERE HAVE YOU BEEN 😊
Color: Grey, Size: 34" - 3 Panel
I purchased RANTILA 3 Panel Room Divider, 6 Ft Tall Folding Privacy Screen Freestanding Room Partition Wall Dividers, 102''W x 20''D x 71''H, Grey. For outdoor use on my patio is perfect . PRIVACY!!! YAY!
It was packaged very carefully. There were no missing parts. Instructions were there but I still had to use the video visually. A few screws would not screw in. So I used a hammer with a few good taps that helped using the screw driver. 😊 It was easy putting it together following the directions. Everything is well made. Love the height, functionality and it’s definitely light it works.
Thank you
