2. Airocide APS-200

The Airocide APS-200 and APS-200 PM 2.5 are two of the most unique types of air purifiers we’ve seen to date. Both use a filterless air cleaning technology, originally developed by NASA for the International Space Station.

Unlike most traditional purifiers, which use filters or ionization, the Airocide draws air into a matrix of hollow glass tubes. When particles contact this surface they break down at the molecular level. This process is called Oxidation (aka Redox) and it notably does not produce ozone.

Below are the other notable features and specs on the Airocide APS-200 / APS-200 PM 2.5.

• Destroys allergens (ex. pollen, pet dander, dust, etc.)
• Destroys germs (ex. bacteria, virus, etc.)
• Destroys VOCs (ex. toxic off-gassing, household cleaners, aerosol sprays, etc.)
• Filterless design, instead uses the Airocide Reaction Chamber
• Airocide Reaction Chamber replacement cost is $129 (lasts 1 year)
• Zero ozone produced
• Auto mode uses light sensors to shift into a quieter setting at night and higher power settings during the day
• 5 year warranty

• Chemicals floating in the air aka volatile organic compounds (VOCs)
• Bacteria & Viruses
• Mold
• Allergens (ex. dust, pollen, and pet dander)

Below is the full list of features included with the Molekule:

How to Choose the Best Air Purifier for You

Wondering how to choose the best air purifier for your needs? To make a well-informed decision, it helps to know exactly what you’re looking for.

Start by asking yourself the 3 questions below.

These questions act as great starting points to making sure that you end up with the air purifier that is right for you and your space.

1. Decide your budget.

The first step is to decide on your budget. There are some impressive air purifiers that make great values priced under $100, while other stretch into the $300-500 range, or some even up to $1,000. Don’t be dismayed if your budget means that you need to stay on the lower side.

Many times, these smaller air purifiers still have impressive filtration systems, but are simply designed for smaller spaces. You can help to remedy this by committing to move the purifier around your space to help maximize its reach and impact.

• For a budget air purifier, check out the Levoit LV-H132.
• For a moderatly-priced purifier, check out the Dyson TP02.
• For a top-of-the-line air purifier, check out the Molekule.

2. Decide the features that are most important.

Different air purifier put their design efforts into a variety of different features. Depending which features are most important to you, may help to drive the decision of which air purifier to select.

Some of the most popular features in air purifiers includes:

Real-time air sensing: With real-time air sensing, the air purifier will be able to constalty access the indoor air quality and determine what level of purifiercation is needed.

An example of an air purifier with real-time air quality sensing is the Coway AP 1512HH.

Remote control: Some air purifiers can be controled remotely with a physical remote control, smartphone control, or even voice control (when paired with a smart device like Amazon Alexa or Google Assistant).

An example of an air purfier with remote control is the Dyson HP02. 

Filter status indicator light: This little light can be a simple addition, but really makes a difference when you’re trying to determine the status of the filters.

An example of an air purifier with a filter status indicator light is the Honeywell AirGenius 5.

Auto mode: Auto mode can be based off of indoor air quality, pre-programmed schedules, or time of day. Essentially, this mode automatically adjusts the fan speed or intensity if purifiercation based on a specific factor.

An example of an air purifier with an auto mode is the Airocide APS-200.

Sleep mode: Sleep mode is a quiter level of purification that allows you to rest easier without high fan speeds stealing your sweet dreams.

An example of an air purifier with a sleep mode is the AirMega 300.

3. Decide which type of purifier will be best for your home.

There are a couple main types of air purifiers on the market, with varying technologies and forms of purification.

Three of the most popular include:

1. HEPA air purifiers: HEPA filtration is the most popular type of air purifier on the market. These filters use an ultra-fine mesh to help filter out ultra-tiny particles, in some cases all the way down to 0.3 microns.
2. Activated carbon air purifiers: There are not many air purifiers that rely solely on activated carbon filters, but carbon purification is highly effective at helping to remove odors from your home. If odor-reducing features are your main aim, you’ll want to make sure you select a purifier with an activated carbon (charcoal) filter.
3. Ionic air purifiers: Ionic air purifiers (aka ionizer) use the power of negative-charged ions to attract to postively charged airborne particles in your room and sink them to the floor, where they can later be vacuumed up. Getting these partcicles out of the air is the first step in preventing airborne illnesses and the spread of germs.
