7 reviews for Arrow 5 UV-LED Water Treatment System

    Acuva water filters are the best use them in my Rv and now my vacation casita as well, the I prefer the larger units because they have higher flow rates but they all are 100x better than dealing with water bottles.

    We have been full time RV’ing in our Airstream for the past 3 years. During that time, we had a Berkey water filter system, that worked well, but took up a lot of counter space, and was becoming burdensome to constantly stash away when we traveled. My wife is very particular about water taste, so we started looking at more options. We came across the Acuva water filtration system, and decided to give it a try. We ordered it, and within the week, it was delivered. The installation took just a few hours (I had to squeeze it into a tight spot), but was straight forward with directions, and fairly simple to accomplish. It has freed up a bunch of counter space, and we are both quite pleased with the taste of the water. We both wish we had installed the system three years ago when we first bought our trailer!

    This is my third UV filter by Acuva. I use them in my RV to sanitize the drinking water. They have been reliable and work well. The install is easy. I did call support once for a question and they were very helpful. Its a great product.

    We are so happy with our Acuva Arrow 5 in our converted coach bus. It was super easy to install and doesn’t take up much space under our sink. We’ve been using it with well water from our property, which can be quite stinky, and we are very impressed with how clean the water tastes and smells. I feel good that this will keep our drinking water safe as we are about to begin full time travel and will be getting water from various different sources and you just never know what the water will be like. We’ve used other water filters in the past and the convenience and low maintenance of the Acuva system really appealed to us. I can highly recommend this system!

    I recently purchased the Acura Arrow 5. Ordering was easy and I received my unit fast. I had a minor problem with the unit (it was missing one of the tubes). I called customer support and that day, they shipped the missing part, and a free pre filter to make up for their error! The customer service is outstanding. The unit is well made and was very easy to install. They have a YouTube installation video online that is super easy to follow. I would highly recommend the Acura Arrow 5!

    Nice product, works as designed, easy to install.
