Best Air Purifiers Under $100: Buying Guide

Understanding Types of Air Purifiers

When looking for the best air purifier under $100, it’s essential to understand the different types available on the market. There are three main types: mechanical filters, electronic air purifiers, and activated carbon filters.

Mechanical filters use HEPA or High-Efficiency Particulate Air filters to trap and remove particles from the air. These are excellent for capturing allergens such as pollen, dust, and pet dander.

Electronic air purifiers use ionizers or electrostatic precipitators to charge particles in the air, causing them to stick to surfaces or collection plates. They are effective in removing smoke and odors but may generate ozone as a byproduct, which can be harmful to your health.

Activated carbon filters utilize porous carbon to absorb gases and odors from the air. These are great for eliminating cooking smells, volatile organic compounds (VOCs), and tobacco smoke.

Key Features to Consider

When choosing an air purifier, these are some of the key features to look for:

  1. Area coverage: Determine the size of the room where you plan to use the air purifier. You’ll want a device capable of handling the room’s square footage. Air changes per hour (ACH) is another important metric to consider, as it indicates how often the air in the room is replaced.
  2. Filter type: Based on your needs and the types of pollutants you want to target, decide which type(s) of filters are best for your situation.
  3. Noise level: Noise levels typically range between 30-60 decibels (dB). If you’re sensitive to noise, look for a purifier with a lower dB rating or one with a night/quiet mode for bedtime.
  4. Energy efficiency: To save on your electricity bill, look for air purifiers with energy-efficient labels or ENERGY STAR-certified models.

Consider Maintenance and Replacement Costs

Finally, it’s important to consider the maintenance and replacement costs of filters.

Mechanical filters, like HEPA filters, typically must be replaced every 12 months, depending on usage.

Activated carbon filters should be replaced more frequently, usually between 3-6 months.

For electronic air purifiers, there may be a washable pre-filter but also a need for occasional replacement of collection plates.

By taking into account these factors and features, you can find the best air purifier under $100 that suits your needs.

Investing in a good-quality air purifier can provide you with cleaner, fresher air, ultimately improving your indoor air quality and promoting a healthier living environment.

Best Air Purifiers Under $100: Final Thoughts

Choosing the best air purifiers under $100 can be a daunting task, but with a little bit of research, you will find the perfect one for your needs.

It’s essential for you to consider factors such as the size of your room, filter replacement costs, and noise level before making the final decision.

Remember, a good air purifier can improve your indoor air quality, help you breathe easier, and promote a healthier environment for you and your family.

Don’t forget to compare features, read customer reviews, and ensure that the product you choose meets your requirements.
