A water purifier comes in handy when you start to consider the quality of your water or where it’s sourced. While it’s true that your public water system probably has a purification protocol already, the quality of results leaves a lot to be desired. The treatment used and the state of water pipes are factors that can diminish the water quality in the long run.
Treating and purifying water has been a common practice throughout history. But now, the technology has grown to be affordable for home use. Some water purifiers are even as small as a pencil, so you can have clean water on the go! In the article below, we’ll provide you with our best picks on the top water purifiers, as well as a buying guide so you can select which one is best for you.
Water filters and water purifiers are not the same thing. Although both filter out impurities like sand, a purifier one-ups a filter by removing microorganisms as well. These are often waterborne bacteria and viruses such as Salmonella and E. coli. Some purifiers can even remove the chlorine that comes from a public water system.
However, water purifiers require more discretion. Because most involve the use of chemicals for treatment, it’s important to find a model with a good build quality. This is so that they won’t leak when subjected to high temperature or high-pressure water.
Here are some key points to consider:
For more detailed information, read through our buying guide below.
To find the best water purifier, it’s best to check the water quality of your home first. Water, especially from the tap, can contain different contaminants. You will need a specific kind of purifier depending on the contaminants you have. Thankfully, this is easy to figure outーyou can ask your local provider or test it yourself with a water testing kit.
Reverse Osmosis (RO) purifiers are directly connected to your plumbing. They're especially effective in removing Total Dissolved Solids (TDS), which is the amount of inorganic and organic material in your water. Some examples of these are trace metals and bacteria. These are filtered out with a semi-permeable membrane, and current RO systems can have a filtration rate of up to 99% or higher.
However, these systems don't clean out water mixed with foreign liquids like chlorine and pesticides. As such, it's best to pair these systems with activated carbon to remove over 70 kinds of these contaminants.
Another downside is the amount of water waste produced. Approximately four liters get discarded for every one liter purified. Fortunately, you can use the water waste for other tasks like washing clothes and watering plants to cut back on your water bill.
Other than TDS, tap water can be contaminated by bacteria and other waterborne organisms. An ultraviolet purifier, as its name suggests, contains a UV lamp where water passes through for purification. The ultraviolet light destroys most of these pathogens, making sure that your drink will be disease-free.
However, most of these types don’t come with a filter. This makes them less efficient in cleaning out solids in the water like dust and sand. Plus, the dead bodies of the pathogens remain in the purified water—harmless but can be off-putting. As such, ultraviolet purifiers are ideal if your water quality has a TDS level below 100.
A gravity-based purifier is as precise as it sounds. The device is composed of two chambers: one above and one below. You pour the contaminated water into the top chamber, and using gravity, it slowly drips into a filter. By the end of the process, you’re left with purified water in the bottom chamber.
These systems are convenient because of their simplicity. They come in many sizes, thus supporting various use cases. Plus, because they don’t need electricity to function, you can use them anytime. However, take note that these can be less effective than their electrically-powered counterparts. As such, it’s best to use these for relatively cleaner water, with a TDS level below 200.
Like reverse osmosis purifiers, an ultra-filtration device uses a membrane for purification. However, as it uses screen-like fibers, it only succeeds in capturing large sediments and bacteria. This makes it inefficient in filtering hard water, which is water with a high mineral content like magnesium and carbonate salts.
You’ll be glad to know, though, that these systems work with no electricity. They also come in varying sizes, making them capable for several storage locations. Just remember to regularly replace the filter at least twice a week to ensure optimum purification.
Activated carbon uses charcoal that has been divided into small pieces. This material has a natural adsorptive property and is thus used to attract chemicals and metals present in the water.
However, because activated carbon alone functions poorly against dissolved salts and sediments, it’s instead used as an aid for other purifiers. By blocking damaging particles and acids, these ensure that your product will have a longer shelf life.
Most high-filtration purifiers work with electricity. As such, it’s important to consider how much water the device can hold, especially when living in an area prone to power cuts. Higher storage capacity generally means a heavier price tag and a bigger place to put it, but this ensures that you’ll get purified water for the duration of the blackout.
Most water purification systems come with built-in filters. These separate the purified water from any solid residue such as trace minerals and dead viruses—generally, the smaller the pore size, the lesser the contaminants that make it through the process.
While your optimal pore size will vary from region to region, a good approximation is 1 micron or less. The pores here are small enough to trap particulate matter, though some smaller microorganisms might make it through. If you suspect your water needs a more precise filtration, it’s best to consult a professional to know the best filter size for you.
Water purifiers come in a variety of shapes and sizes. Depending on which you get, you’ll find that each form factor offers a different kind of use case. Below, we list down the advantages and disadvantages of each one.
These are the newest trend in the water purification world. They work by emitting UV light through a light wand sticking out of the device. It then kills any harmful microorganisms within a liter of water. Light, compact, and easy-to-use, these products are best used on the go.
Just remember that these don’t come with a built-in filtration system. That means that the water will still be contaminated with sediments, minerals, and the dead bodies of the microorganisms. Thankfully, you can get external filters for maximum protection—or check out other form factors below.
Pitcher purifiers are not connected to your plumbing, making them portable and handy. This is best for people who want a no-nonsense system, since you just pour water and let the device do the work.
However, when going for these types, we recommend sticking to an ultraviolet or reverse osmosis model. These ensure that all microorganisms are killed. Unfortunately, with other variants, the contaminants will still be active, just stuck to the filter. This is riskier, as they can seep into the water after some time.
On-tap purifiers have become popular because of their simplicity. Most simply attach to your faucet and can filter out 378 liters before needing a filter replacement. Plus, because they’re easily detachable, you can switch between purified and unpurified water depending on your use case.
The downside is that many of these suffer from durability issues. Cheaper models have plastic housing, making them break easily under high pressure and high-temperature water. Plus, despite their universal design, some users have experienced a loose-fitting product, so it’s best to measure your faucet first.
As the name implies, countertop filters sit beside your sink. There are several variants available, though the most common are either ones that attach to your faucet or one that’s filled with water. Either way, they shine as a cost-effective purification system.
They can, however, be a source of clutter. Depending on the product, they can take up a significant chunk of your sink space. Plus, most of these are electrical, so you’ll have to be more careful when handling them to avoid electricity-related accidents.
Under-the-counter filters are often installed under your sink. They connect directly to your plumbing and send the purified water to their own specially-installed faucet. Furthermore, while performance may vary, these generally surpass the purification from other systems. Some products even claim to reduce 99% of contaminants.
These, however, require a more in-depth installation. Most of the time, users would rather hire a professional rather than risk damaging their plumbing. Plus, these systems require a reservoir, so make sure that your sink has enough space underneath.

Below are some of the most asked questions on the web answered by the mybest team.
This ultimately depends on the amount of water you consume, the product you're using, and the amount of contaminants in your water. We recommend checking your product's manual for specifics, though a good rule of thumb is to change the filters every two months or every 40 gallons.
Short answer: yes! In fact, simply boiling rainwater kills most germs, although this doesn't remove any chemicals present. As such, we recommend a product that not only kills or filters out microorganisms, but also comes with activated carbon. This removes the toxins in the rainwater to ensure safe consumption.
Aside from general cleaning and maintenance, be sure to check the pressure nozzle occasionally. A water pressure that's too weak or too strong can potentially damage the pipes of your purifiers. You can also sanitize the water storage tanks every time you replace the filters, simply to make sure that no debris has bypassed the filters.
Mineral water contains nutrients like calcium, magnesium, and sodium that most water purifiers filter out. That said, it can also contain 10 times more bacteria than tap, especially if the containers are being reused.
We recommend checking with your local supplier if they meet health standards. Otherwise, it may be best to purify your mineral water to avoid potential hazards.
Even with the best purifier, you won't get all the benefits of water if you drink it wrong. Yes, surprisingly, there are mistakes we can make when drinking! This video by Dr. Eric Berg highlights everything you need to know and the steps you can do to improve how you drink. Here they are in a nutshell:
If you're looking for other ways to enjoy clean water, there are other options out there to keep you hydrated. Our top picks below are not only healthy but come in a ready-to-drink bottle-no purification needed. Their refreshing taste is also a welcome thirst-quencher against the Philippine heat!
Water is a commodity many overlook, but that shouldn't be the case. What you're drinking right now contains millions of chemicals and microorganisms that can affect your well-being. Thankfully, water purifiers exist to protect you from these dangers.
The right product will not only improve the health benefits of your water; it can even improve flavor, too. It can change your water from flat-tasting to refreshing, and from metallic to pure. That said, we hope that our recommendations and buying guide have informed you enough to find what will give you the cleanest, freshest water for your home.
