What Are the Most Important Things to Know Before Buying an Air Purifier?

There are several important things to know when shopping for an Air Purifier. It is not just about the features; It’s about how effectively the device cleans your air based on your specific needs, such as airborne pollutants, Dust, pet dander, mold spores, and even wildfire smoke. Let’s explore the key factors you should consider before making a purchase.

1.Filtration System Type

The filter is the heart of an air purifier, and the best option is a HEPA filter (specifically, True HEPA) because it removes 99.97% of airborne particles as small as 0.3 microns.

Activated Carbon Filter

The Carbon filter eliminates odors, smoke, and VOC’s (volatile organic compounds)

Pre-Filter

The pre-filter is responsible for capturing large particles and helps extend the life of the HEPA filter.

UV Light or Ionizer (optional)

This type is used to kill bacteria and viruses, but some models may emit ozone, so it’s important to check for safety certifications before purchasing.

Tip: Our suggestion is to look for True HEPA+Activted Carbon is the best combo for most homes.

2. Check For CADR Ratings

CADR stands for Clean Air Delivery Rate. A higher CADR means faster and more efficient air purification. It measures the volume of filtered air delivered per minute, typically in cubic feet per minute (CFM)

CADR ratings usually cover three types of airborne particles and each of has its own CADR score tohelp you compare performance across different models.

Smoke CADR: 200 CFM (smallest particles)

Dust CADR: 220 CFM (medium particles)

Pollen CADR: 250 CFM (larger particles)

Space-Wise CADR Recommendations

Small Room (up to 150 sq.ft): Look for CADR 100–150

Medium Room (150–300 sq.ft): CADR 150–250

Large Room (300–500 sq.ft): CADR 250+

Tip: CADR should be at least 2/3 of your room’s square footage.

Example: If your room size is 300 sq.ft Then Look for a CADR of at least 200.

3. Noise Level

The ideal noise level for bedrooms is between 25–40 dB, which is considered quiet. However, some models can become noticeably noisy when operated on high settings.

4. Smart Features

Smart features are optional but they can be very helpful. These may include air quality sensors, app or voice control, and auto mode, timer, or sleep mode for added convenience and efficiency.

5. Filter Replacement & Cost

Filters typically need to be replaced every 6–12 months. Some air purifiers may have a low upfront cost but come with expensive replacement filters, so it’s important to check the filter availability, replacement cost, and ease of access before buying.

6. Ozone Emission

Avoid models that emit ozone (some ionizers do), as it can irritate lungs, especially for asthma or allergy sufferers. Look for CARB certified (California Air Resources Board) for ozone-safe devices.

7. Brand Trust

The trust brands are like Levoit, Blueair, Dyson, Alen, Honeywell, and Shark NeverChange
