The ProOne Big+ is a life-saving device. One of the most harmful contaminants in tap water is chlorine. Although this is used to disinfect your city water and kill all the pathogens, it still leaves traces behind.

So, you are drinking something that can potentially kill all the good bacteria in your body, too. So, fluoride is the next most important thing you need to filter out from your water.

Besides these, you must ensure pesticides, bacteria, heavy metals, lead, pathogen parasites, nitrates, and more than 200 harmful things are eliminated from your water. The

It can hold up to 3 gallons and can filter it out in one hour. The water tastes fantastic and is very different from other filtered water.

The next thing that you will love about the ProOne is that it has all-white ceramic filters. With these ceramic filters, you don’t need to buy separate fluoride filters. These are all in one. These filters are also interchangeable with a couple of other famous water-purifying filters.

The filter has a 0.3 micro-ceramic filter on the top, removing sediments, rust, bacteria, and other floating particles.

Then, you have a six-stage filter underneath it. The first layer is activated alumina, which removes up to 99% of fluoride and does not put aluminum back in the water.

Then there is activated carbon, which does the bulk of the work to remove the bacteria, chlorine, pharmaceuticals, trihalomethanes, odors, taste, and all the other junk in there.

Next, there is another part that removes heavy metals from the water. In the end, you have fan stones that can suspend or neutralize other heavy metals as well as oxygenates.

To add to this, some stones will add calcium, magnesium, and other trace minerals. Finally, natural silica or sand acts as a polish to the water and an overkill secondary water filter. Finally, at the bottom, you have stones.

Next, the Santevia filters have a life span of 12,00 liters which is around four months of usage in a household of three people.

The Ceramic filter on the top is good for one year, and the stones at the bottom are good for two years. This does end up costing more, but you get what you pay for.

6. Sawyer Gravity Water Filtration System

Sawyer Gravity Water Filtration System review

It is convenient and does an excellent job of providing you with drinking water on the go instead of making you go back to the water source plenty of times.

Let us talk about the one-gallon bag itself first. Now, filling this bag up is not super convenient. Just dunking it into the water source will not help. You need to have a smaller container to help you fill this up. It takes a lot of time to fill in a gallon with a small container. The handle placement concerning the water nozzle is also a little awkward.

One of the other things that come with this bag is the Sawyer mini, modified to make it more convenient for gravity filtration.

You can screw this onto the filter bag and then run the water out of the filter and into your desired container. Of course, it can also be opened and closed according to your users also.

The flow rate is a bit slow but remember, the slower the water flow, the more authentic the filtration water. It gives out water consistently. Next, you have a hose that can be screwed onto the filter to hang your filled bottles eventually.

You also get the backflush syringe, a double side threaded coupler that allows you to flush using a smart water bottle.


  • Easy to use.
  • Consistent water flow.
  • Suitable for backpacking.
  • Great quality.


  • Inconvenient bag.
  • Limited application.

You can use it as a receptacle. You can use the water filter straw individually, too, with any other unit.

It has a nice long handle making it easy to scoop out water. Then, fold it from the top and clip it. Make sure you prep the filter properly before you start the filtration process.

Hang the gravity filter in a high place and let the filter do its job. To stop the filtration process at any point, all you have to do is re-cap, and this way, the water will remain in the bag. In addition, it gives you the option to filter water as you go.

What is a Gravity Water Filter? 

There is a lot of different type of water filtration processes out there. As the name suggests, a gravity water filter uses gravity to pull water down through layers of filters, purifying and filtering it in the process.

How Does a Gravity Water Filter Work? 

Gravity water filters purify water through a multiple-stage water purification process. The number of stages may depend on the kind and number of filters in your specific model. The system proceeds without using any harmful chemicals or a power source like electricity or gas.

Initially, you fill up water in your unit through the top. Once the water is added, gravity pulls it down. The water then goes through different filters and stages.

If your device has a ceramic filter,2, then that successfully filters out almost all impurities. In addition, some have separate carbon filters, sediment filters, and even fluoride filters.

Once the water passes through these stages, all the impurities that need to be removed are removed. The foul taste and smell also reduce to a below identification level. Next, most filters use stones and sand to add extra minerals to your water, giving it the desired freshwater taste.

Essentially, gravity pulls water downwards, making it go through filtration and purifying stages in a gravity water filter.
