We’ll compare popular filter types like under-the-sink, countertop, faucet, pitcher, bottle and straw models. You’ll learn technical specifications like micron ratings, lifespan and flow rate. 

Additional considerations like weight, capacity and special features will also be covered to help you select the ideal water filter for home, travel or outdoor use. Let’s dive in to demystify water filtration so you can drink easily with a filter you can trust.

Filter Types and Uses

Water filters come in a variety of configurations designed for specific uses:

Under Sink Filters

Under-sink water filters connect directly to your main water line for unlimited filtered water on demand. Convenient and effective, they’re one of the best options for whole-home filtration. Leading brands are Aquasana, Aqua Blue and Puretec.

Countertop Filters

Countertop filters sit on your kitchen counter or tabletop and connect to your faucet or supply line. They include pitchers or bottles combined with multistage filters. Culligan, Aquagear and Filtered make top countertop models.

Faucet Filters

These attach directly to your existing kitchen faucet. Simple to install, just turn on your faucet for instant filtered water. Leading faucet filter brands include Brita, PUR and Culligan.

Water Pitchers

Pitchers with built-in filters are affordable and easy to use. Fill them up in your sink, then refrigerate for great-tasting filtered water on hand. Pitchers from Brita, Clearly Filtered and Aqua Gear are customer favorites.


Water Bottles

Portable water bottles with filters are ideal for travel and outdoor activities. They filter from lakes, streams or taps for clean water on the go. LifeStraw, Grayl and Sawyer make top-rated portable filter bottles.

Water Straws

Similar to bottles, straw-style filters let you drink directly from lakes or rivers. No pumping or waiting – just sip filtered water through the straw. Leading brands are LifeStraw, Sawyer and Survivor Filter.

Micron Ratings

A filter’s micron rating determines what it traps – the lower the microns, the tinier the particles it removes. A good filter should remove contaminants down to at least 0.5 microns. The best trap particles as small as 0.1 or even 0.01 microns.

Filter Capacity

Determine how much water you need to filter. Smaller filters, like bottles, work for personal use. For families, opt for high-capacity pitchers or under-sink models that can handle more daily use. Check manufacturer specs for lifespan and flow rates.

Filtration Stages

More filtration stages mean more contaminant removal. Basic filters have 1 stage. Advanced systems have up to 7 stages combining activated carbon, UV light, reverse osmosis and more for maximum water purification.

Weight and Portability

If travelling or backpacking, lightweight straws, bottles or folding filters are ideal. For home use, pitcher and faucet filters are easy to move, but under-sink and countertop units are fixed installations.

Special Features

Keep an eye out for useful touches like filter change reminders, quick connect fittings for easy installation, recyclable parts and QR codes for filter authentication. The more convenience built in, the better.
