What to Know Before You Buy an Under Sink Water Filter
Under sink water filters are convenient when you want clean, safe water to drink but don’t have enough space to install a whole house water filter. What you must know, however, is that some of these filters are also large, so before you get one, make sure you have enough room under the sink. Some customers installed the devices in kitchen cabinets or even garage walls.
Another thing you should consider is whether you want a reverse osmosis under sink water filter. The RO technology is the best you can choose if you deal with moderate-to-severe water contamination levels. While whole house filters deal best with mildly contaminated water, RO systems strip the water of almost everything, from heavy metals to viruses and even radioactive elements.
Other tech specs and features you should also consider are:
- Filter life – the bigger, the better;
- Installation – some filters require plumbing and skills, while others feature easy installation;
- Environmental value – while it is true that reverse osmosis system do waste some water, under-sink water filters can remove the need to buy plastic water bottles for months and even years. Make some math and see what filter saves the largest number of water bottles and money.

Whether you want a unit that can deal with mild contamination or something that can get your drinking water as pure as possible, there is something for you on our list.
