Which Filter Should You Choose?

Read on below for a quick look at the different types of filters. Remember to search for filter models in the NSF database.

Types of Filters

Unsure which filter is for you? Let’s walk you through the main types.

Faucet Filter vs. Pitcher Filter

Both are almost similar in function, but faucet filters are a little better than pitcher filters.

You can attach a faucet filter yourself. Faucet filters provide cleaner water and have a longer life. You can turn them on and off to use regular unfiltered water.

Faucet filters also give you filtered water the moment you turn on the faucet. There’s no pitcher you have to fill and keep refilling, unlike pitcher filters.

That said, not every faucet filter will fit every faucet. They can also reduce water pressure.

Whole House Filters

A whole house filter (reverse osmosis filter) provides you with clean water to drink and to shower with. This will spare your hair and skin the rough elements in normal water, especially hard water.

Drinking and washing are not the only things you need clean water for. A whole house filter lets you cook with clean water, which is safer and tastes better.

A quality whole house filter requires very little maintenance. It also helps give your plumbing a longer life and prevents buildup in your sink and bathtub.

Undersink Filters

Undersink filters are made specifically to fit under your sink. They can remove far more contaminants compared to other types of filters, except for the whole house filter.

Unfortunately, under sink filters emit wastewater. We recommend a whole house filter that fits under your sink.

Does My Tap Water Need Filtering?

If your tap water tastes or smells foul, it could be contaminated. Not all contaminants can be tasted or smelled, however. You and your family may be drinking contaminated water without knowing it.

Your best bet is to send a sample of your tap water to one of the many certified laboratories that will test your tap water for you and determine how contaminated it is.

What Do Filters Remove?

Water filters remove impurities such as dirt, silt, sediments, and sand. Depending on the type of filter, they also remove chlorine, pesticides, arsenic, bacteria, and viruses. Some filters can also remove iron, manganese, and sulfur.

After you send out a sample of your water to be tested, you’ll get a water quality report detailing the levels of inorganic metals, microbes, and lead in your tap water. Your report will also list the safe level for each contaminant.


Here are a few common concerns of people considering a water filtration system.

Are water filters dangerous?

Water filters that are not NSF-certified can be dangerous. As long as you’re buying from a reputable manufacturer, quality water filters are safer than tap and bottled water.

Is filtered better than bottled?

Filtered water is safer for you and better for the environment. Bottled water has reached 2000 times the price of tap water. It can also contain double the amount of contaminants in tap water. Unlike tap water, bottled water isn’t FDA-regulated.

Plastic water bottles are also a major health risk and a major source of pollution. The manufacturing process harms the environment in numerous ways. People throw-away over 60 million plastic water bottles per day. These not only litter but also release toxins as they degrade.

Environmentally concerned people who reuse plastic bottles face health risks because of bacterial growth and toxin release.

Are pitcher filters safe?

Research has shown that pitcher filters only remove between 49% and 80% of the contaminants they claim. They can also introduce bacteria into the supposedly purified water at levels even higher than tap water.

If your immunity is compromised, you should not use a pitcher filter. Faucet filters are in the same price range and a much safer option than pitcher filters.

Are refrigerator filters safe?

Very few refrigerators are as clean as they should be. This means the water from your refrigerator water filter can be contaminated with waterborne bacteria. This exposes you to coliform and salmonella, among other contaminants.

Because the refrigerator water filter isn’t as readily visible as other kinds, you may forget to replace it. This is also bad for your health. We don’t recommend drinking from a refrigerator filter.

What’s the right size filter for my pool?

According to the Pool Cleaner Blog, bigger is always better when it comes to choosing a filter for your pool.

Your best bet is to pick a filter with a bigger capacity than the size of your pool.

Wrap Up

As you can see, there’s no one-size-fits-all filter that removes every contaminant, fits anywhere and has enough capacity to suit every household.

We recommend the APEC Top Tier 5-Stage. Its 40-gallon capacity means a practically unlimited supply of clean water.

This filter removes 99% of contaminants, including arsenic and viruses. It’s also one of the rare water filters that can remove fluoride.

People have reported that the water actually tastes good, much better than bottled water, not to mention most similar products. It fits easily under most people’s sinks and in tricky spaces.
