Replacement Cartridges and Membranes - Reverse Osmosis are also important parts of a small water filtration system.

First and foremost, you need to know what's in your tap water. Tests can reveal contaminants that need to be removed, or simply unpleasant taste and odor.

If you're looking for a filter that just improves taste and odor, check out Consumer Reports' (CR) water filter ratings for filters that score high in flavor/odor reduction tests.

You'll also want to consider the type of contaminants in your water. If tests reveal contaminants, look for a water filter certified to remove those substances. This means the filter has been independently tested and meets a specific standard.

Here are some key factors to consider when choosing a small water filtration system:

Ultimately, the right system for you will depend on your specific needs and budget. Consider your water consumption, the contaminants in your water, and the cost of replacement filters.

We test water filters in a lab by spiking spring water with common compounds that can make it smell and taste bad, like a sewage treatment plant or a swimming pool. A panel of professional tasters then evaluates how well each filter removes those flavors and odors.

We also measure how long it takes to filter one quart of water to determine the filter's flow rate. The faster the filtering, the higher the score.

We give each filter a "clogging" score based on how much its flow rate slows down over the filter cartridge's stated life. This helps us understand how well the filter will perform over time.

We verify claims made by manufacturers about their filters meeting NSF/ANSI standards for removing specific contaminants, such as chlorine, lead, and PFAS.

First, consider what's in your tap water. If tests reveal no harmful contaminants, you can focus on improving taste and odor. Check CR's water filter ratings for filters that score high in flavor/odor reduction tests.

Think about your budget and water consumption. If you need to remove contaminants, look for a filter certified to remove those substances. NSF standards are a good place to start.

Under-sink water filters are certified to reduce lead, and some faucet-mounted filters and water filter pitchers are certified to reduce PFOA and PFOS. Look for the NSF/ANSI standard on the packaging or manufacturer's website.

If you're considering a filter that's not in our ratings, check for a stamp or seal confirming which contaminants it's certified to remove. Third-party labs like NSF, WQA, and IAPMO are reputable certifying agencies.

Countertop filters can be a good option if you're a renter or want a DIY installation. However, be aware that replacement cartridges can cost more than the filter unit itself.

Under-sink filters can clean a higher volume of water at a greater flow rate, but replacement filters can be costly, ranging from $80 to over $320.

Here's a quick comparison of filter types:

Remember, filter cartridges must be replaced periodically to function effectively. Our ratings allow you to compare each product's annual filter replacement cost.

There are various types of filtration systems available, each designed to remove different contaminants from water. Filtration systems can be categorized into several types, including Reverse Osmosis (RO) filters, Nanofiltration, and Ultraviolet (UV) Systems.

Reverse osmosis filters are effective in removing germs and some types of chemicals from water. They work by forcing water through a semi-permeable membrane, which blocks contaminants and allows clean water to pass through.

Some common types of filters include:

The pore size of a filter is another crucial factor to consider. A filter's pore size determines the size of the tiny holes that let water through, and smaller pore sizes are more effective at removing contaminants. For example, a filter with an absolute pore size of 1 micron will block anything larger than 1 micron, while a filter with a nominal pore size of 1 micron will have an average pore size of 1 micron, allowing some larger contaminants to pass through.

When working with filtration systems, it's essential to have the right parts to ensure they function properly.

Replacement parts are available for various filtration systems, including those with Pura UV and VIQUA UV components.

Faucets and filter media are also essential components of a filtration system.

Fittings and housings provide structural support and connection points for the system's components.

O-rings are a type of seal used to prevent leaks in the system.

Pumps are used to circulate water through the filtration system.

Some systems also require an R.O. Booster Pump to increase water pressure.

R.O. tanks are used to store water that has been filtered through the reverse osmosis process.

Here is a list of some common filtration system parts:

Your water quality report, also known as a Consumer Confidence Report, is released every July by your community water supplier. This report tells you if any regulated contaminants are detected in the water and how they compare with the EPA's drinking water standards.

If your house was built before 1986, you may want to do your own tests for lead, as older pipes can be a source of contamination. Recently, the Consumer Product Safety Commission warned consumers about imported faucets that can leach lead.

At least 45 percent of the nation's tap water is contaminated by PFAS, a class of synthetic chemicals that persist in the environment and have been linked to health issues. The EPA established nationwide limits for PFAS in drinking water in 2024, requiring public water systems to monitor six PFAS compounds and take action if levels rise above prescribed limits.

Reverse osmosis filters can remove some types of chemicals from water, including lead, copper, chromium, chloride, and sodium. These filters may also reduce arsenic, fluoride, radium, sulfate, calcium, magnesium, potassium, nitrate, and phosphorous.
