Our Testing Experience

First Impressions

When I first unboxed the Aquasana Under Sink Water Filter System, I was impressed by its compact size. It fit neatly under my kitchen sink without taking up too much space. Installing it was easier than I expected, thanks to the clear instructions. I was curious to see how quickly it would deliver filtered water since I’m used to slower drip filters. Right away, I noticed that the system promised to reduce many contaminants, including chlorine and lead, which made me hopeful about the water quality.

Daily Use

Using the filter every day quickly became part of my routine. I loved how fast it filtered water — no waiting around for a glass of clean water. The chrome faucet looked sleek and matched my kitchen decor nicely. I noticed the water tasted fresher and smoother, with none of the usual chlorine smell. It felt good knowing harmful things like PFAS and pesticides were being filtered out, but the healthy minerals remained. Making coffee and cooking with this water felt better overall.

Key Features in Action

The high flow rate was definitely a highlight for me. Getting half a gallon of filtered water in just a minute was impressive and convenient. I also appreciated that the system didn’t remove all the minerals, so the water didn’t taste flat or bland like some filters can cause. Knowing it reduces up to 99% of 78 contaminants gave me peace of mind about the water my family drinks every day. The filter’s long life—lasting up to 6 months or 800 gallons—also made it feel like a smart investment.

Long-Term Performance

After using the Aquasana filter for several months, I can say it held up well. The flow rate stayed consistent, and the water quality remained excellent with no strange tastes or smells. Changing the filter was straightforward when the time came, and the system still looked and worked like new. It’s been reassuring to know that I’m providing cleaner, safer water without spending a lot of money or dealing with complicated maintenance.
