Frequently asked questions
Short answer: Keo is designed to perform safely in warm water.
Here’s why that matters.
Many standard tap filters rely heavily on carbon-based filtration. While effective in certain conditions, carbon filters aren’t designed for consistent exposure to hot water. Elevated temperatures can reduce their effectiveness and may compromise previously captured contaminants.
Keo was engineered with this in mind. Our filtration system is built to maintain performance in everyday warm-water use — so you can filter confidently, whether you’re rinsing, cleansing, or washing your face.
Smarter design. Safer performance. No compromises.
TLDR: Usually 4–6 weeks, but it depends on your water quality.
Technically, a single cartridge can last a few months if you’re lucky enough to have very clean water. In older homes, buildings, or when using well water, you might need to replace your filter more often. We recommend changing your filter every 2 months or as soon as you notice reduced water pressure, whichever comes first.
TL;DR: From $39 USD — and one 5-pack can last about 6 months (per filter).
We offer two cartridge pack options:
- 5-Pack — $39 USD
- 10-Pack — $59 USD

You’re billed every 4, 6 or 12 months, and you can modify or cancel your subscription at any time — no lock-ins.
Depending on your water quality and usage, a 5-pack typically lasts around half a year per household, making it a simple, low-maintenance replacement schedule.
TLDR: Dirt, microplastics, rust, bacteria, gunk, chlorine, and chloramines.
The Keo filter is engineered to stay effective even under high water temperatures.
As water flows through the system, it first passes through a 5-micron sediment layer that captures dirt, rust, bacteria, microplastics, and other debris — particles up to 10× smaller than a grain of sand.
At the same time, the water interacts with 99.5% pure, food-grade Vitamin C, which instantly neutralizes chlorine and chloramines.
This dual-action process delivers cleaner, safer, and more refreshing water — all in one seamless flow.
TLDR: Yes! We guarantee a 100% faucet fit 🙌 If you need extra adapters, we’ll send them free of charge ❤️
Our filter is designed to work with both hidden and exposed faucet aerators.
If the included adapters don’t fit, simply fill out the form via the Installation QR code that comes with your Keo Filter, and we’ll ship you a custom adapter right away — at no cost.
Not sure if your faucet is compatible? Send a photo of your aerator to keofilters@gmail.com and we’ll gladly check it for you 😊
TL;DR: Yes — it’s made for both drinking and everyday use like washing your face and brushing your teeth.
The Keo Filter is designed to reduce chlorine, sediment, micro-impurities, and other unwanted contaminants — making your water cleaner whether you’re drinking it, brushing your teeth, or washing your face.
Compared to standard tap water, filtered water from Keo is noticeably fresher and gentler for daily use.
