Why Choose a Budget Air Purifier in 2025?
Indoor air can be up to five times more polluted than outdoor air, according to the EPA, with allergens like dust, pollen, pet dander, and smoke contributing to respiratory issues or allergies.

These units are typically priced under $150, with low maintenance costs, making them accessible for budget-conscious buyers. Features like quiet operation, washable pre-filters, and occasional smart controls enhance their value.

How to Choose the Best Budget Air Purifier in 2025
Selecting the best budget air purifier depends on your room size, air quality needs, and budget. Consider these factors:
