Top Affordable Air Purifiers of 2023: Breathe Easy for Under $100

Air purifiers are devices that help remove contaminants from the air in a room. These machines are commonly marketed as being beneficial to allergy sufferers and asthmatics, and at reducing or eliminating second-hand tobacco smoke. The purifiers function by filtering and trapping harmful particles and contaminants, circulating the clean air back into the room.

Here’s how they typically work:

1. Use of filters: Most air purifiers use a system of internal fans to pull the air through a series of filters that remove harmful airborne particles like dust, pollen, and bacteria. The air purifier then circulates the purified air back into the room.
2. Different types of filters: These can include a HEPA filter (High-Efficiency Particulate Air) capable of removing at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm). Other filters might be designed to neutralize or absorb various chemicals, toxins, or odors.
3. Ionizing purifiers: Some air purifiers use ionizers—meaning they release negatively charged ions into the air causing pollutants to settle on surfaces, theoretically cleaning the air. However, this technology is sometimes controversial because it may produce ozone, a potentially harmful byproduct.
4. UV lights: Certain models use ultraviolet lights to kill viruses, bacteria, and molds that pass through the air purifier. However, they’re not typically effective against non-living allergens or chemical fumes.
5. Adsorbents: Some air purifiers also include adsorbent materials (like activated carbon) that can help with odors, fumes, and chemical pollutants.
6. Size and room capacity: Air purifiers come in various sizes and designs, with certain models built to clean the air in a single small room and others designed for larger or multiple rooms.

Air purifiers work by moving air through filters that capture harmful airborne particles like dust, pollen, pet dander, mold spores, and bacteria. The basic mechanism involves drawing in air, passing it through a series of filters, and then expelling the purified air back into the room.

Here’s a more detailed look at the process:

1. Fan or air circulation system: Most air purifiers use a system of fans or a blower to pull in air from a room. The air is then circulated through the unit. Some air purifiers operate very quietly, while others might produce a low-level noise, similar to a fan or air conditioning unit.
2. Pre-filter: The first line of defense in many air purifiers is a pre-filter, which captures larger particles like hair and large dust particles. This stage helps protect finer filters from clogging with these larger particles and extends the life of the main filter. In many models, pre-filters are washable or vacuumable.
3. Main filter: The most common type of main filter is the HEPA (High-Efficiency Particulate Air) filter, which captures 99.97% of particles as small as 0.3 microns. This filter traps smaller particles like dust, pollen, pet dander, and mold spores, and is a standard for high-quality air purifiers.
4. Additional filters or technologies: Many air purifiers also include additional filtering technologies:
   • Activated carbon filters absorb gases, odors, and chemical toxins. The carbon particles in these filters chemically bind to gas molecules and remove them from the air.
   • UV-C light can kill bacteria, viruses, and other microbes by damaging their DNA. It’s often used in combination with filters rather than as a standalone solution because it doesn’t trap particles.
   • Ionizers emit negative ions, causing pollutants to stick together and become heavy enough to fall out of the air or stick to surfaces. Some ionizers produce ozone, which has its health concerns.
   • Ozone generators are a type of air purifier that intentionally produces ozone, which reacts with certain pollutants to neutralize them. However, ozone is a lung irritant and can be harmful to health, so these are not recommended for general use, especially in residential settings.
5. Clean air release: After the air passes through these filters, the clean air is circulated back into the room, usually through a vent. The process repeats several times an hour, continually reducing the number of airborne contaminants.

It’s important to note that the effectiveness of air purifiers in removing harmful particles varies depending on the specific technology used, the unit’s size, the room size, how well the room is sealed, and how often the air purifier’s filters are changed. Regular maintenance and proper use, as per the manufacturer’s instructions, are crucial for the unit to function effectively.

Benefits of Using an Air Purifier

Using an air purifier can have several benefits, particularly in indoor environments where air quality is compromised due to pollutants, allergens, or other harmful particles.

Here are some of the key benefits:

1. Allergy Relief: Air purifiers help reduce the concentration of airborne allergens, which are common triggers for allergies and asthma. By trapping or neutralizing pollen, dust, pet dander, and other allergens, these devices can alleviate allergy symptoms for many individuals.
2. Smoke and Odor Removal: Smoke from cigarettes, cooking, and external sources like wildfires can contain harmful particles. Air purifiers with activated carbon filters can absorb smoke and associated odors, making the indoor environment more pleasant and healthier.
3. Support for Respiratory Health: By continually cycling the air and reducing the concentration of pollutants that can irritate the respiratory system, air purifiers can contribute to healthier breathing environments, particularly for individuals with respiratory conditions, the elderly, and children.
4. Reducing Airborne Diseases: Certain models of air purifiers are effective at capturing and neutralizing bacteria and viruses. While they are not a standalone solution for disease prevention, they can be part of a broader approach to reduce the spread of illnesses, especially in communal or densely populated settings.
5. Elimination of Harmful Chemicals: Volatile organic compounds (VOCs) are emitted by a variety of household products, building materials, and furniture. They can have short and long-term health effects. Air purifiers equipped with the appropriate filters can reduce the concentration of VOCs in a room.
6. Improved Sleep: Better air quality can improve sleep quality by alleviating congestion, reducing potential allergens, and creating a more comfortable environment conducive to good sleep.
7. Overall Well-being: Cleaner air means a healthier environment for all individuals, potentially leading to overall improvements in well-being. This can be particularly noticeable for people who suffer from health issues related to air quality.
8. Reducing Stress and Enhancing Mood: Breathing clean air can also have a psychological benefit. Knowing that you’re taking care of your living environment can reduce stress and enhance mood, contributing to overall mental health.

It’s important to note that while air purifiers can significantly contribute to a healthier indoor environment, they should be part of a holistic approach to indoor air quality. This approach includes proper ventilation, regular cleaning, maintaining optimal humidity, and minimizing the use of products that emit harmful chemicals. Also, the effectiveness of an air purifier depends on its proper use and maintenance, including regular filter changes.

Choosing the Right Air Purifier

Choosing the right air purifier depends on several factors, including your specific needs, the size of the space, and the types of pollutants you need to address.

Here’s a guide to help you make an informed decision:
