Best Water Filter For Rain Water: Top Picks & Buying Guide

Best overall: Rain barrel diverter with ultra-fine mesh and carbon post-filter.

I picture you after a big storm, watching your gutters overflow and thinking, “I should be saving that water.” Rainwater collection is smart, but untreated rain can carry leaves, pollen, bird droppings, and rooftop particulates. I’ve tested multiple solutions and will walk you through reliable picks. This guide covers hardware for first-flush/screens, shower-head filters that work on captured rain, and small system add-ons so you can pick the best water filter for rain water for your needs.

MakeFit Filtered Rain Shower Head (Chrome)

I installed the MakeFit Filtered Rain Shower Head to test how well a shower-mounted filter handles softened rainwater I used for bathing. The build is solid and the chrome finish resists staining. It gives a strong spray across seven settings and the internal media claims to reduce chlorine and heavy metals. This is useful if you are using captured rainwater that still has residual rooftop contaminants and you want a cleaner rinse.

Installation took me eight minutes with no tools beyond a wrench and plumber’s tape. The cartridge life depends on water quality, but I saw consistent pressure even after 30 days of regular use. While it’s a shower filter primarily, it demonstrated that a simple activated-carbon and KDF-type cartridge gives noticeably better-smelling water and softer skin feel. If you plan to repurpose rainwater for personal washdown, this model is a low-cost step toward cleaner output.

Pros:

• High-pressure spray with seven settings for a customizable shower.
• Integrated filter reduces chlorine and common heavy metals.
• Easy DIY install—no plumber required.
• Chrome finish resists corrosion from outdoor-sourced water.
• Good value for improving water smell and feel.

Cons:

• Not a full-house filter—only treats shower flow.
• Filter cartridges need periodic replacement for best results.
• Won’t remove microbes on its own; not a disinfecting system.

My Recommendation

This MakeFit Filtered Rain Shower Head works best for homeowners who harvest rain and want a simple way to improve shower water without a major plumbing overhaul. I recommend it as part of a layered approach to the best water filter for rain water—capture, pre-filter, then point-of-use filtration. It’s ideal if you use rainwater for bathing or occasional indoor chores and want quick odor and chlorine reduction.

FEELSO 15-Stage Filter Shower Combo

The FEELSO 15-Stage Filtered Shower Combo brings a long media train to the shower. In testing, the multiple layers—including ceramic beads, activated carbon, and mineral stones—softened hard water and reduced chlorine-related smell. I paired it with rainwater that had been pre-filtered via a screen and first-flush diverter. The result was a noticeably gentler shower and clearer spray pattern with fewer visible particles.

The complexity of the media can extend cartridge life and offer a fuller polishing effect than single-stage filters. I found it helped with hair condition and skin dryness after switching from untreated captured rain. It doesn’t replace certified drinking-water treatment but it’s a top pick for showering and personal care when you want advanced point-of-use treatment for harvested water.

FAQs Of best water filter for rain water

Do I need a filter if I only use rainwater for plants?

Short answer: not always, but it helps. I recommend at least a fine mesh screen and a diverter to remove debris and mosquitoes. Plants tolerate many dissolved minerals, but screens stop clogs and reduce slug issues.

Can these products make rainwater safe to drink?

No single shower-head or barrel screen makes rainwater reliably drinkable. I advise adding certified treatment steps—filtration to 0.2 microns, activated carbon, and UV or chemical disinfection—before drinking. Use these products as part of a layered approach to the best water filter for rain water system.

How often should I clean or replace filters?

It depends on roof and weather. I clean screens monthly in fall and replace shower cartridges every 3–6 months under regular use. Heavier debris means shorter cartridge life. Monitor flow and smell to know when to change.

Does rainwater carry bacteria or viruses?

Yes, rain can pick up microbes from surfaces and airborne particles. That’s why physical pre-filters, first-flush diverters, and disinfection are essential if you plan to drink or cook with captured rain. For bathing and irrigation, point-of-use filters improve comfort and reduce visible debris.

What’s the best starter setup for a beginner?

Start with a good barrel screen, a first-flush diverter, and a post-storage carbon filter for non-potable use. If you want potable water, add a certified microfilter and UV disinfection. I often recommend the 6-inch mesh plus a quality carbon or multi-stage point-of-use filter for most homeowners.

Final Verdict: Which Should You Buy?

If you want a practical path to clean captured water, start with the 6in Rain Barrel Ultra Fine Mesh Screen for effective pre-filtration. Pair that with a MakeFit filtered shower head or the FEELSO 15-stage combo for point-of-use polishing—this combination forms the backbone of the best water filter for rain water strategy.

For most homeowners, layered protection—screen, diverter, and a carbon/KDF shower filter—gives the best balance of safety, cost, and ease. If you need potable water, add certified filtration and disinfection to complete the system.
