Although air purifiers have become more popular in recent years due to their role in improving indoor air quality, their health effects are frequently questioned. Learning about how these devices work and the health impacts they may have can help you protect yourself and your family.

Air purifiers do a great job of removing indoor allergens, dust, and air pollutants. Their performance is conditional on proper maintenance and the type of filter installed. Addressing each of these criteria ensures that air purifiers provide genuine value.

That considered approach produces a real-world remedy for cleaner air in your environment.

What Are Air Purifiers?

Air purifiers are machines that filter and clean the air in your home by trapping particles and chemicals. They often remove airborne particles such as dust, pollen, mold spores, and bacteria.

By targeting these, air purifiers help ensure cleaner, healthier air in homes, offices, or any other indoor environments.

They are not a magic bullet; different models and technologies target different needs.

There are many different kinds of air purifiers on the market. HEPA filters are extremely effective at seizing microscopic particles.

They capture particles down to 0.3 microns and 99.97% of them are taken out.

This quality makes them great for removing fine dust or allergens.

Carbon filters are the most effective at removing odors and gases.

By comparison, ozone generators do provide powerful odor elimination but are often criticized for being unsafe. Advocacy groups and experts such as EH&S strongly advise against ozone-based options due to harmful health effects.

Air purifiers suck in air, capture harmful contaminants, and release healthier air back into the home.

HEPA filters, for example, trap difficult-to-remove particles, and carbon filters absorb odors at the molecular level.

The clean air delivery rate (CADR) measures how well an air purifier works.

It’s a way to measure how much-filtered air the air purifier can deliver per minute.

For truly effective air purification, a CADR that matches at least two-thirds the size of your room is a must.

It’s important to note that air purifiers can provide an important supplement to ventilation, but should not be considered the most effective standalone solution.

Do Air Purifiers Have Health Risks?

Some air purifiers may aggravate respiratory ailments such as asthma or allergic rhinitis, particularly if they generate ozone. Ozone generators sold as air purifiers can even damage your lungs and decrease your ability to breathe, especially harming those with serious health problems.

As the EPA cautions, particulate matter—those microscopic particles in your indoor air—can lead to dangerous health risks. Breathing in these particles can cause short-term lung irritations and potentially permanent damage.

HEPA filters, which trap those very particles, are a good bet, though not every purifier is HEPA-certified.

Some models are even designed to recirculate even smaller particles back into the room, completely reversing the benefit of cleaner air. Therefore, ozone-generating purifiers should be of particular concern.

Environmental Health & Safety (EH&S) organization cautions against these devices due to the fact that ozone can worsen existing respiratory symptoms. Studies show air ionizers can reduce particulate matter but may negatively affect cardiovascular health, causing trade-offs between benefits and risks.

Long-term effects are still unknown, and experts such as Delphine Farmer urge for more research before widespread use.

Benefits of Using Air Purifiers

Air purifiers are a smart, easy way to start enjoying cleaner indoor air. They work hard to filter out allergens, dust, and smoke particles from the air in your home.

Whether you suffer from pollen allergies or reside in regions affected by wildfires, an air purifier can greatly improve your quality of life.

You’ll enjoy cleaner air to breathe, thanks to its high-performance filtering right harmful particles.

This is particularly important for people with preexisting conditions, such as asthma.

Studies reviewed by the EPA have found clear and sizable improvements in respiratory health.

Certain air purifiers are specifically engineered to remove certain pollutants.

Models that use HEPA filters do a great job at capturing pet dander.

At the same time, activated carbon filters filter out VOCs emitted by products like paint and cleaners.

With portable units, it’s convenient to bring better air quality wherever you go.

It’s an easy way to improve the air quality in your bedroom, office, or any other space.

Factors to Consider Before Buying

variety of features that make up a quality air purifier
  • Save

When shopping for an air purifier, there are a variety of features that make up a quality air purifier. To begin with, the type of filter matters.

High-Efficiency Particulate Air (HEPA) filters are great at removing nearly every particle in the air. Their remarkable MERV rating, nearly 16, is the primary consideration for their efficacy.

Many models include removable pre-filters. They catch bigger particles such as dust and pet hair, which safeguard HEPA filters and make them last longer.

Activated carbon filters have an enormous surface area of more than 100 acres per pound. These filters are highly effective for odor and VOC removal.

Second, consider the purifier’s noise output. It is typically around 24 to 36 dB which means it won’t bother the peace and quiet of your home.

How well it fits your room size is a third consideration. AHAM recommends that the CADR (Clean Air Delivery Rate) should be sufficient to condition at least two-thirds of the room’s square footage. This guarantees maximum impact.

Maintenance is a third, but equally important, consideration. HEPA filters require changing every 6-12 months, based on usage.

Pre-filters, since they are less expensive, typically need to be cleaned or replaced every 3 months. Ignoring these can make the purifier far less effective as time goes on.

Make sure the unit is easy to access for maintenance and cleaning. Make sure replacement filters are easy to find!

Energy efficiency has a significant impact on lifetime costs. To be sure you’re using less electricity, look for units with Energy Star ratings.

Models that let you control fan speed and set a timer can save even more energy.

Cost comparison is equally important. Some cheap models may incur more maintenance costs with the need to regularly replace filters.

More expensive units often come with more durable features, such as washable filters and longer-lasting parts.

These incentives make implementing these benefits extremely cost-effective and can save you substantial money in the long run.

For instance, an air purifier with a reusable pre-filter might make up for its greater upfront cost in savings from lower replacement costs.

How to Maintain Your Air Purifier

Proper maintenance of your air purifier will not only help it work more efficiently, it will extend its lifespan.

Taking care of your air purifier will help you avoid expensive damage and protect your air quality for years to come.

First, change your filters according to the recommendations from the manufacturer. These filters usually need to be changed every six to twelve months.

In comparison, carbon filters only last three to six months.

Cleaning the unit’s exterior is equally as important. Wipe it down with a damp cloth to clear off dust and debris that could clog vents or sensors.

Periodic inspections are required as well. Check the airflow and listen for any strange sounds.

For an adapter unit, we recommend replacing UV lamps every 12 months to keep them running at peak performance. You’ll need one lamp, two lamps, or even four lamps, depending on the model.

IonicAir models require a specific care routine. Don’t forget to periodically tap or flick the bi-polar brush heads to clean them, and check that you’re replacing the AHPCO-5G3 cell every 2 years.

In addition to changing filters, it’s important to protect whatever space the air purifier is in.

Locate it where there is enough open space around it, away from walls or furniture, to enable airflow to circulate freely. This is the only placement that keeps the Clean Air Delivery Rate (CADR) at its peak performance level.

The CADR tells you the speed at which the device filters air.

For typical size rooms, find a unit with a rate of 1,100 to 2,200 cubic feet per minute (CFM). These units can remove 99.97% of particles down to 0.3 microns in size. This includes allergens such as dust, pollen, and even bacteria.

Keeping a simple log of your maintenance activities will make this step a breeze.

Keep a record of when you replaced filters, and UV lamps, and when you last cleaned them.

This simple practice will keep you ahead of the game and will make sure that your purifier is running at its full potential.

If you’re ever sensing a decrease in performance, check to see what the history tells you. This will let you know when a filter change or other maintenance is due.

Alternative Ways to Improve Air Quality

Improving air quality can be simple, such as increasing ventilation.

Daily opening of windows and doors also brings in fresh outdoor air, helping to lower concentrations of indoor pollutants.

Adding fans or air conditioners can improve that air exchange even more, helping make sure pollutants don’t linger trapped inside.

Ensuring your home is properly ventilated is one of the simplest and most impactful ways you can help create healthier air.

Or you can remove pollution at the source by cutting what causes it.

Tobacco smoke, strong cleaning chemicals, and even some types of candles can all pump harmful chemicals into the air.

Making the switch to natural cleaning methods and eliminating synthetic air fresheners can be an important step to eliminate these toxins.

In the same way, combating odors at their source instead of covering them up benefits air quality and quality of life.

Consistent cleaning practices go a long way too.

Dusting and vacuuming surfaces, particularly rugs and fabric-covered furniture, can help remove allergens such as dust mites.

Cleaning with vacuums that have HEPA filters, which trap at least 99.5% of particles 0.3 microns and larger, gives added peace of mind.

Keeping surfaces free of dust, particularly in overlooked areas, provides an extra layer of confidence.

Humidity control is the other big one.

Mold and dust mites love moisture, so keeping humidity levels between 40%-60% reduces the chances of them taking over.

Tools such as dehumidifiers can control moisture levels, creating a less hospitable environment for these allergens.

Finally, think about adding a whole-house air filtration system.

Unlike portable purifiers, these systems become part of your home’s HVAC configuration, offering ongoing, effective air filtration without the need for extra equipment.

Usually, they come with HEPA filters, so you can breathe the cleanest air possible throughout your entire home.
