Why We Love It
- Multi-filtration: Our upgraded composite car wash filter contains superior resin. Several stages of filtration efficiently reduce harmful elements such as chlorine, aluminum, cadmium, magnesium, iron, lead, mercury and other heavy metals, as well as sediments. This filtered water will better protect the paintwork of your car.
- Efficient Cleaning: The AQUACREST inline car wash water filter boosts the power of your detergent, and effectively reduces water spots caused by air-dried minerals after you wash your car or clean your yard. The 5-micron filter aperture can efficiently filter out impurities and produce quality water. The upgraded formula prolongs the filters service life and storage, thereby ensuring long-lasting, clean, and hygienic use.
- Meeting Your Outdoor Needs: Professionally developed for outdoor cleaning, the filter is ideal for car washing, window washing, yard and fence cleaning. It also fits pressure washers. To save money, use this filter to wash your vehicle instead of relying on expensive car washing services. In addition, the upgraded filter is smaller and lighter than the traditional filter, so you wont need a cart and activating resin. *NOT recommended for drinking, fish farming.
- More Cost-effective: The inline car wash filter has a lower average weekly cost than expensive car washing services, thereby saving you money. The upgraded formula prolongs the service and storage life of the filter, ensuring long-lasting, clean, and hygienic use.
- Adding Hose Protector: The anti-kink flexible hose protector can prevent the water pipe joint from twisting. The result is smoother flowing water and a better filtration experience. The protector can also prevent the water pipe joint from damage and improve the service life of the filter, saving you money in the long run.
- Perfectly Fitting Your Equipment and Long-lasting Service Life: The inline filter fits any standard 3/4" garden hose thread. Youll enjoy clean and fresh water while protecting the paintwork of your car and beautifying your yard.
