MicronFlo works two ways — as a replacement cartridge for most standard inline shower filter housings you may already own, or paired with the Rainley Bossa housing for a complete starter setup. Either way, swapping in a new cartridge takes under a minute with no tools.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eStandard dimensions: 2.68\" x 2.4\" x 2.4\" — measure your current cartridge to confirm fit before purchasing.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eWhat makes MicronFlo different from every other replacement cartridge is what you can see. The transparent body lets you see the white pleats change as they capture contaminants, turning amber, brown or grey depending on your local water. In some homes the change is only slight. This built-in visual indicator means you replace the cartridge based on actual buildup, not an arbitrary subscription schedule. You're in control.\u003c\/p\u003e\n\u003cp\u003eAt the core of MicronFlo is a two-stage filtration mechanism. The outer pleated membrane uses mechanical sieving to capture particles as small as 5 microns — 14x finer than a human hair — including microplastics, sediment, rust, pipe scale, and sand that loose-media filter beds let slip through. Once pre-filtered by the pleats, water enters the inner chamber where KDF-55, Calcium Sulfite, and Activated Carbon Fiber work to reduce chlorine, chloramines, heavy metals, pharmaceutical residues, and chemical impurities that contribute to dry skin, scalp irritation, frizz, color fade, and hair thinning.\u003c\/p\u003e\n\u003cp\u003eMicronFlo is designed for both municipal tap water and private well water, including hard water conditions. It is especially effective for customers managing sensitive or reactive skin, eczema, dandruff, psoriasis, color-treated hair, keratin treatments, and post-salon hair investments they want to protect.\u003c\/p\u003e\n\u003cp\u003eCartridge life depends on your household size and your local water. MicronFlo is rated for up to 10,000 gallons under EPA-defined moderate contaminant conditions, but that's an upper limit, not a countdown. Smaller households usually get more life, while homes with high-sediment or well water may need to replace sooner. Watch the pleats, not the calendar.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat MicronFlo reduces:\u003c\/strong\u003e chlorine, chloramines, heavy metals, iron, rust, sediment, pipe scale, microplastics (particles larger than 5 microns), and hydrogen sulfide.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat MicronFlo does not address:\u003c\/strong\u003e nitrates, fluoride, arsenic, or biological contaminants requiring UV or reverse osmosis treatment. MicronFlo is not a substitute for whole-home water treatment or well water disinfection. Customers with known nitrate or arsenic contamination in their well water should consult a certified water treatment specialist.\u003c\/p\u003e\n\u003cp\u003eMicronFlo does not affect your home's incoming water pressure, which is determined by your municipality or well infrastructure.\u003c\/p\u003e\n\u003cp\u003eTrusted by homeowners, renters, RV travelers, hair salons, nail salons, gyms, and spas seeking cleaner water for skin, hair, and nail treatments.\u003c\/p\u003e\n\u003cp\u003ePatent pending — USPTO #18\/778,307\u003c\/p\u003e","brand":"Rainley","offers":[{"title":"Default Title","offer_id":45617404280984,"sku":"198715338782","price":40.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/1997\/0456\/files\/MicronFlo_main_padded.png?v=1790682096"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/1997\/0456\/collections\/Micronflo_main.png?v=1790668167","url":"https:\/\/rainley.com\/collections\/cartridges.oembed","provider":"Rainley","version":"1.0","type":"link"}
