Why is A9 Plus more expensive than other water filters?
A9 Plus is a premium, tankless reverse osmosis system built with durable materials and advanced technology. Unlike cheap units that clog, leak, or slow down, A9 Plus delivers fast flow, ultra-pure NSF-certified 0.0001μm filtration, and smart features — all backed by a 3-year warranty. It’s a long-term investment in your family’s health and convenience, often saving money compared to bottled water.
How does A9 Plus improve the taste of my water?
By removing chlorine, PFAS, heavy metals, fluoride, and microplastics, A9 Plus transforms tap water into crisp, refreshing water that tastes like premium bottled water — without the waste. It also eliminates limescale, so tea, coffee, and cooking taste better.
Is it noisy or slow like other RO systems?
Not at all. A9 Plus is engineered for quiet operation and delivers a fast 1000 GPD flow rate, meaning you can fill a glass in seconds, unlike older tank systems.
