How to Choose a Portable Air Purifier

If you’re looking for a portable air purifier, there are a few things you need to know. In this article, we’ll go over how to test a portable air purifier, compare HEPA and non-HEPA filters, and discuss energy consumption and cost. We’ll also cover what features are most important to you. If you have a specific health concern, consider buying one that has HEPA filters.

Tests of portable air purifiers

Tim Walsh of the Wirecutter website conducted a series of tests involving various air purifiers. His tests involved placing the air purifiers at a secluded area, approximately 7 feet away from walls and at least 20 feet from the ceiling. He then measured the air quality in the room by burning five matches, which is similar to the air quality in an open-plan office. He also ran each machine for one hour, and recorded the particle counts in increments of one minute.

The researchers employed professional-grade equipment to test the efficiency of each purifier, including an HEPA-based filter. The HEPA filter is particularly effective against these particles, resulting in a nearly particulate-free air flow. The particle count of the device is determined by CADR (the Comparative Air Dust Reduction) measurements, which show the air purifier’s efficiency. A high CADR means the air purifier is able to filter out particles as small as 0.09 microns.

In a study of the Mighty air purifier, the unit reduced particulate matter by 99.9% within an hour. On the other hand, the Airmega 400 lowered particulate load by 0.2% on medium. These results support the company’s claim that running a portable air purifier for one hour on high or two hours on medium produces clean air. These results, however, are not indicative of an effective purifier for every situation.

Clean Air Delivery Rate (CADR) is a widely accepted international benchmark for comparing the efficiency of air-purifiers. In Canada, CADR is reported in cubic feet per minute (cfm) and cubic metres per hour (m3/hr).

The Coway Airmega Icon air purifier is due to launch in the late second quarter of 2022. It integrates a wireless charging station and is aimed at spaces up to 320 square feet. In contrast, the Levoit Core 600S is a higher-end version of the Core 400S. The Core 600S is targeted at living-room spaces. Its high CADR is due to its advanced technology.

HEPA versus non-HEPA technology

When choosing a portable air purifier, you should consider the difference between HEPA and non-HEPA technology. While HEPA is better at removing larger particles, non-HEPA technology can still capture some of the smallest particles. If you’re looking to catch some of these gases, look for an air purifier with a carbon filter. Higher fan speeds and longer run times mean better filtration.

The difference between HEPA and non-HEPA technology is in the size of the filter. HEPA filters are made of a very fine glass thread, typically less than one micron in diameter. They tangle together to form a filter mat. The threads are microscopic, so a large portion of the mat is made up of air. In addition, the openings in a HEPA filter are typically less than 0.5 microns, which makes them very effective at catching even microscopic particles.

The main difference between HEPA and non-HEPA technology in a portable air purifier is the level of efficiency. A portable air purifier with a HEPA filter is 90% efficient, which is much higher than a non-HEPA one. The high efficiency of the HEPA filter gives the owner peace of mind knowing that the unit will work as it should for a long time. Keeping maintenance costs low is another advantage of using a portable air purifier with HEPA technology.

A portable air purifier with HEPA technology is the best choice for removing large particles in the air. This technology is more effective at removing particles of this size and does not release any harmful chemicals. The difference between a HEPA and non-HEPA portable air purifier is not as dramatic as you may think. If you have asthma, you should consider buying a portable HEPA purifier to eliminate the toxins in your air.

Another important consideration is cost. Compared to non-HEPA technology, a HEPA portable air purifier is much cheaper than a non-HEPA one. However, the HEPA filter must be replaced regularly. The cost of a HEPA air purifier depends on the efficiency of the filter. Unlike the ionic filter, the HEPA filter is less expensive than a non-HEPA unit. The HEPA filter must be replaced if it becomes clogged with particles.


If you’re on a budget, you might consider a small, portable air purifier. While they may not be as powerful as larger models, they can still remove allergens, dust, and smoke. Some models even remove pet dander. If you’re concerned about the cost, consider the following factors. Read on to learn how to find the best portable air purifier for your budget. It might surprise you to learn that they can save you a lot of money over their lifetime.

A whole-house air purifying system can cost anywhere from $400 to $4,000, depending on the efficiency of the filtration system, how large your home is, and the installation. Whole-house HVAC purifiers are expensive, but they’re also very effective at removing allergens. You can save money by purchasing an Energy Star-certified model that has the added benefit of reducing your energy costs. Many brands have warranties that last from one to five years, but remember that these warranties are void if you don’t install your unit yourself. Portable ionization units, on the other hand, produce ozone gas, which is harmful in high concentrations.

Portable air purifiers can be cheaper than whole-house systems and can be used wherever you go. However, not every budget can accommodate a whole-home air cleaner with HEPA filtration system. Buying a portable air purifier is more cost-effective than installing a unit, and will save you money in the long run. And because portable air cleaners aren’t permanent fixtures, you can easily bring them with you when you travel.

Another type of portable air purifier is the Blueair Blue Pure 411+ Air Purifier. It uses a HEPA filter and activated carbon filter to clean up to 185 square feet in 12 minutes. This unit comes with a washable fabric pre-filter. You can choose between white, blue, and green filters, and it’s Energy Star-rated. Its one button control makes it easy to use and a convenient remote for controlling the machine’s settings.

Energy consumption

The power consumption of a portable air purifier is lower than other household appliances such as televisions, refrigerators, air conditioners, and water heaters. On average, a 50 watt air purifier uses 0.05 kW of electricity a day. However, this number can fluctuate depending on how many hours you run your air purifier for. For comparison, a typical television consumes 70 watts per hour, a 50 kW air purifier uses 0.05 kW of electricity, and a 600 watt air conditioner consumes 2000 kWh of electricity.

A study was conducted in six US homes to determine whether the energy consumption of a portable air cleaner is significantly different in auto versus manual mode. The study used a multivariate mixed-effects model to account for confounding variables. The study found that the continuous operation of the PACs in the residences recruited for the study consumed about 5 kWh of energy per month. The auto mode was found to consume 3% more power than the manual mode.

The DOE uses annual sales data for consumer air cleaners to determine the economic impacts of the proposed energy conservation standards. To calculate the energy savings from these new standards, it collects data on the number of portable air purifiers in the United States. The DOE also uses data on the number of units sold by ENERGY STAR qualified companies over a five-year period. The data is then analyzed using the DOE’s data.

In addition to the price of a portable air purifier, the power consumption depends on how big the room is. A large room may require several air purifiers, each of which uses electricity at varying levels. A 15 watt air purifier can reduce the electricity consumption by nearly half. But if you are concerned about energy consumption, you can always use it on low or medium settings. ENERGY STAR regulates the energy consumption of portable air purifiers, and a typical air purifier will use about 550 kilowatt hours per year. This is comparable to a desktop computer or a standard refrigerator.

A typical water heater uses 0.3 kWh per hour, and a portable air purifier consumes 0.3kWh per hour. This means that a mid-priced air purifier may cost you between $3 and $8 a month. However, it will pay for itself within a few months of operation. The best way to find out your portable air purifier’s energy consumption is to buy a model with the lowest energy consumption.
