Review: I really love my Pro One Gravity water filter. It a huge difference in the taste of the water. It is so conventional on the kitchen counter.
Review: So far this filter has been so easy to use. I never have to worry about filter water for about three days or more. The water taste great and I am saving money on buying plastic water bottles. I use other filters in the past from sink filters to plastic refrigerator filter containers but nothing as fresh tasting as this. It’s a bit pricey but worth it in the end. You can place this anywhere in your house and have the family have a glass of water when ever they want. What I do is put a glass gallon container that fit in my refrigerator and refill it every three days and the rest of the water I use for cooking or ice. Two filters I find enough for me but you can you three in the tank. I’m only a household of two but I can see this working well for a larger family as well.

## Questions & Answers

**Q: How do I set up my ProOne gravity filter for the first time?**
A: Scrub each filter under cold running water without allowing water to go inside the blue stem. After scrubbing your filters, cycle 3 batches of water through them and dump the water. Start drinking your water on the fourth cycle for the best taste.

**Q: How do I prep my ProOne gravity system for travel?**
A: Allow your filter elements to dry out, then wrap them in a cloth and store them in a safe place. If you store filter(s) inside the gravity system, make sure they have ample padding to prevent breakage.

**Q: How often should I clean my gravity systems and filters?**
A: We recommend cleaning your systems and filters at least once a month.

**Q: When and how should I store my filters?**
A: If you are not using your filters or system for more than 4–7 days, drain the water and air-dry the filters. Wrap the filters in a terry cloth towel and store them in a cool, dry place. Do NOT put them in a plastic bag or any enclosed container.

**Q: How many filters should I use?**
A: Each ProOne G2.0 filter has a general lifespan of up to 6 months with daily use. Using more filters at a time will increase their lifespan and flow rate at the same time. Using 3 filters at a time will provide the fastest flow rate.

ProOne Big+ Gravity Water Filter System High Capacity Countertop Stainless Steel Water Filter Dispenser IAPMO Certified to Reduce Lead, Total PFAS, Microplastics, Chlorine Taste & Odor, 3 Pack Filter I bought the ProOne Big+ gravity system because I wanted a countertop option that didn’t require installation and had certified filtration. The stainless-steel build feels solid and well-made. Setup was straightforward, and I like that it doesn’t require electricity. The water tastes noticeably cleaner and smoother compared to straight tap water, especially with chlorine taste reduced. One thing to note: it does take some time for the water to filter through, so it’s not instant. But the large capacity makes up for that since you can fill it and let it run. I also appreciate that the filters are IAPMO certified and tested to reduce lead, PFAS, microplastics, and chlorine taste & odor. That gave me more confidence compared to generic filters. PROS: Large capacity Stainless Steel how much it filters CONS: filters little pricey does take up space Overall, it’s been a practical addition to my kitchen and something I use daily.
