Air Ionizer Buying Guide: How to Choose an Air Ionizer Machine for Clean Air Benefits

Pollution affects our health, but how many of us do something about it? Buying an air ionizer (also called an air ioniser, depending upon where you live) is the first step towards cleaner air and a healthier life. To help protect sensitive people from pollen, cigarette smoke, mites and dust, air ionizers are recommended. Air ionizers work similarly to an AC, absorbing the air through a fan and passing it through multiple filters before releasing it back out.

The difference between an ionic air purifier and a regular air purifier is that it generates enormous amounts of electrons, forming an appropriate amount of negative ions and effectively collecting particles in the air. These devices are available in a wide range of models and offer different levels of air filtration.

You might have a dehumidifier if you live in a humid climate. Or it's always good to open the windows every morning in your house in order to freshen the air and after that turn on the air ionizer to take care of the rest. If you spend more time in your car than in your house, there are also car air purifiers out there too!

Important Note: Despite what it says in this video, HEPA filters capture close to 100% of bacteria in the air, as well as a smaller percentage of viruses. Many hospitals use HEPA filters to reduce bacteria and other pathogens in the air. WireCutter did release an update once this video was posted with this correction.
Before purchasing an air ionizer, consider how much you're willing to spend. The more features the air ionizer has, the more you'll have to pay for it. Another thing you will have to decide is whether you actually need an ionic air purifier or whether a HEPA purifier is enough. Additionally, you can opt for an ionizer and purifier combination machine. You will pay more for the ionic functionality in most cases.

Prices range from $40 to $500 for high-end air ionizers. Obviously, we also came upon some cheap air ionizers during our research, but decided to ignore them as they're made from poor quality materials and are not efficient.
Why use air ionizers? This is the question when it comes to purchasing such a product. Among the particles filtered and removed by such products are dust, dust allergens, various bacteria and viruses, pollen particles, airborne microorganisms and pet hair (you will need a HEPA filter if you want all those benefits of an air ionizer).

Air ionizers can also remove cigarette smoke and unwanted odors from a room, while preventing mold and mildew. Additionally, there has been research that suggests that negative ions can have a positive effect on moods, anxiety and performance.

Here are the most important features to look for when buying an air ionizer:
  • Coverage - The amount of treated air is important to determine which is the best air ionizer for you and your family. Generally, it's good to check what type of space it is recommended for: offices, industrial premises, small rooms etc.
  • Filtration system and functions - Filtrations systems must be made of quality materials and easy to change. A good filter would be a combination of carbon (as it eliminates the odors) and HEPA filters, which are extremely effective in removing fine airborne impurities and allergens.
  • Adjustable Speed - A good air ionizer features at least 3 speeds: turbo, medium and small, to help you when you need it the most. An air ionizer with adjustable speed is great for 2 reasons: it helps to lower the power consumption and the device won’t be so loud.
Other features such as dimensions, noise level, and having a remote control will help you in transporting and using the device.

Trivia for You: Many people also use salt lamps or have Tourmaline crystals in their home because of they have a property that releases negative ions in the air. While the evidence is not conclusive, they both can add a nice decorative touch to your home.

Construction and Design
Most air ionizers are designed to operate silently. If yours starts to make noise, you should clean it and change the filters.

These devices are generally lightweight and allow you to move them from one room to another. Most of them weigh between 5 to 20 pounds, feature a handle and can be placed on the floor.

Quality air ionizers feature HEPA filters, which can capture the finest particles. However, you'll have to replace these filters annually if you want them to be efficient.

When choosing the right air ionizer, your comfort should be first priority. Many devices alert you when filters need replacing. Also consider an air ionizer that has a timer so you'll be able to program your device to function for a limited time. Some models also feature a remote control.

Good quality air ionizers use an air quality sensor that allows them to adjust the fan speed according to the particle density in the air so you won't have to adjust the speed manually.
Performance and Ease of Use
An efficient air ionizer will keep the air in your home clean and free of dust, odors and allergens. They’re easy to use: just place them in the desired room and turn them on. However, taking into account that such a device will stay permanently connected to the outlet, it is good to consider the energy consumption. Most models consume between 25 and 50 watts.
