What to look for in a budget air purifier

1. Filtration Type

Look for purifiers with a true HEPA filter, which can capture up to 99.97% of airborne particles. Some models also include pre-filters or activated carbon filters to help reduce odors and VOCs.

2. Room Size Coverage

Check the recommended room size for each model. Many affordable air purifiers are designed for small bedrooms or offices, so make sure the unit matches your intended space.

3. Noise Level

If you plan to use the purifier while sleeping or working, consider its noise output. Many budget-friendly models offer quieter operation on lower fan settings.

4. Maintenance Costs

Factor in the cost and availability of replacement filters. Some low-cost purifiers use proprietary filters that may be expensive or hard to find, so check how often they need to be replaced.
