If you want to protect your health and your family, buying a water filter is the right option. The best water filters can not only remove harmful contaminants in your water, including lead and mercury but also give a better taste of water. Therefore, don’t skip this article if you want to get some more ideas about this excellent product.


If you look up for a water filter on the Internet, you may be overwhelmed by the variety of products and models offered. However, in general, there are four common water filters, which are activated carbon filters, reverse osmosis, alkaline/ water ionizers, and UV filters.

1. Activated carbon filters

Activated carbon filters, also known as carbon filters or pre-filters, are in charge of absorbing large particles such as sediment, organic substances, agricultural chemicals, and silt in your water so that it will be clean. In particular, they also help reduce the amount of chlorine and chloroform in water and make it less odor and tastier for drinking.

Nowadays, to maximize effectiveness, many manufacturers have made activated carbon filters in conjunction with other methods. Aquasana Whole House Water Filter System is a great example. It is promised to 97% of chlorine and reduces harmful contaminants like lead, mercury, herbicides, pesticides, VOCs, and more to bring you the best quality of water.

2. Reverse osmosis filters

Reverse osmosis filters are indeed the best water filters, which can remove all kinds of harmful contaminants to your health. However, these filters usually use an excessive amount of water and cause a decrease in water pressure due to the low process. Therefore, basically, these filters may work well for the necessary needs for clean water such as cooking and drinking but not all daily activities such as showering or washing.

If you are looking for a reverse osmosis filter, this is our recommendation for you: WECO HydroSense Light Commerical Reverse Osmosis Water Filter System. It is equipped with automated water pressure sensors and booster pumps keep the system functioning at maximum capacity.

3. Alkaline/ water ionizers

Alkaline or water ionizers use a special process called electrolysis. When coming through the filters, the water is electrically charged and changed into two different streams: alkaline and acidic. Thanks to this process, these filters not only soften your water but also reduce the acid level in your water, which is better for your skin.

Are you still confused about water ionizers, why don’t you choose Aqua Ionizer Deluxe 9.5 Anti-Oxidant Boost Water Ionizers? This excellent water filter offers you with special features such as high antioxidants, 7 healthy water options, and advanced 9-electroplate technology.

4. UV filters

Unlike other previous filters, UV filters use new and environmentally friendly technology. They use ultraviolet radiation to kill all the bacteria and viruses that are bad for your health. However, it’s important to note that these filters cannot remove other harmful contaminants, so you are advised to apply this filter together with other types of water filters to guarantee healthy and drinkable water for your family.

If you want an environmentally friendly option for your house, a UV filter may suit you the best. And we totally suggest you with Bluonics 110W UV Ultraviolet Light + Sediment & Carbon Well Water Filter Purifier System. This filter is strong, powerful, and especially safe as it does not use any chemicals to treat your water.

1. Water quality

Understanding your tap water quality is the first guide to help you decide which water filter you need. If you are experienced, looking and tasting your water may help you identify the initial problems such as odor, a taste of chlorine, and visible particles on surfaces. Or else, you can ask your current neighbors and residents about their water source to better understand.

2. Your budget
