Air Purifier and Humidifier Options
Understanding What Your Home Needs
Many customers ask about the difference between air purifiers and humidifiers. Here's the simple answer: they serve completely different (but complementary) purposes.
Air Purifiers: Remove contaminants from existing air allergens, dust, pet dander, smoke, odors, and pollutants. Essential year-round for anyone with allergies, asthma, or air quality concerns.
Humidifiers: Add moisture to dry air. Helpful during winter months when heating systems dry out indoor air, causing dry skin, sinus issues, and static electricity.

Your Air Purifier Buyer's Guide: Making the Right Choice
Choosing an air purifier can feel overwhelming with so many options available. We've put together this guide to help you navigate the key factors and find the perfect fit for your home.
What to Look for When Choosing an Air Purifier
AHAM Verified CADR Ratings
Start here. CADR (Clean Air Delivery Rate)measures how quickly an air purifier filters air. It's tested and verified by AHAM (Association of Home Appliance Manufacturers) for three pollutants: tobacco smoke, dust, and pollen. The higher the CADR number, the faster the air purifier cleans the air in your room. Look for models with CADR ratings that match or exceed your room size and air quality needs. This is what separates effective air purifiers from marketing claims.
Sealed System Design
An air purifier is only as good as its ability to draw air through the filter. Look for units with sealed systems that prevent air from bypassing the filter. This ensures all air passing through gets properly cleaned. If air leaks around the filter, pollutants get reintroduced into your space.
Filtration Technology
HEPASilent™ technology is your best friend here. Blueair's signature approach combines mechanical filtration (which physically traps particles) with electrostatic filtration (which uses an electrical charge to make particles stick to filter fibers). This combination is more efficient than mechanical filtration alone; it captures particles faster, operates more quietly, and uses less energy.
Understanding Room Size: AHAM Recommendations
When manufacturers recommend a room size, they're using a standard called AHAM, which bases recommendations on achieving 4.8 air changes per hour. This means the air purifier completely filters all the air in that room about 5 times each hour. Here's what that translates to across different room sizes:
Room Category
Coverage Area
CADR Rating
Best For
Extra Small
Up to 180 sq ft
100-150
Bedrooms, offices, compact apartments
Small
180-250 sq ft

Nurseries, small bedrooms, home offices
Medium
250-400 sq ft
200-300

Extra Large

400+
Great rooms, lofts, and combined living spaces
Pro tip: If you live in an area with high outdoor air pollution or have severe allergies, choose a model with coverage for a room slightly larger than what you need. This gives you extra cleaning power when you really need it.
HEPASilent™ Technology: Your Filtration Advantage
HEPASilent™ isn't just a buzzword; it's genuinely different from traditional HEPA-only filtration. Here's how it works and why it matters:
The Mechanical Part: Standard HEPA filtration uses densely packed fibers to physically trap particles. It works, but it requires a lot of resistance, which means fans need to work harder, creating more noise and using more energy.
The Electrostatic Part: Blueair's electrostatic stage gives particles a slight electrical charge. When these charged particles contact the filter fibers, they stick more readily due to electrostatic attraction. This means the filter can be less dense while still catching particles.
The Result: The combination removes 99.97% of particles down to 0.1 microns while operating 67% quieter and using less energy than traditional HEPA alone. If you have noise concerns (especially in bedrooms) or worry about running costs, HEPASilent™ makes a real difference.
FAQs
What's the best air purifier?
The best air purifier has HEPASilent™ technology, appropriate room coverage (check CADR ratings), and activated carbon for odors. For allergies, choose models with high pollen CADR ratings and sealed systems that prevent air bypass.

Purchase directly from our collection with free shipping, 30 day home trials, and manufacturer warranties. All products are authorized dealer items with expert support available.
What are the best air purifiers for different needs?
For allergies: HEPASilent™ + high pollen CADR. For pets: HEPA + heavy carbon. For smoke: 5+ lbs activated carbon. For large spaces: 300+ CADR rating.
What is the top-rated air purifier?
Top-rated models feature AHAM Verified CADR ratings, True HEPASilent™ filtration, 4.5+ star reviews, and certifications from the Allergy & Asthma Foundation. Check our "Best Sellers" filtered view.
How much are air purifiers?
Portable units: $99.99-$699.99, depending on coverage and features.
Do Air Purifiers Work?
Yes, air purifiers absolutely work when you choose the right one. The key is selecting a unit with verified CADR ratings from AHAM and a sealed system design. Independent testing consistently shows that AHAM Verified air purifiers effectively reduce airborne pollutants by 99.97%.
Do Air Purifiers Help with Dust?
Absolutely. Dust is one of the three primary pollutants that air purifiers are tested and rated for. If you have noticeable dust buildup, that means dusty air is circulating in your home, and an air purifier captures that dust before it settles on your furniture and belongings. CADR ratings for dust measure exactly how effectively a unit removes dust particles from the air.
Are Air Purifiers Worth It?
For people with allergies, asthma, or air quality concerns, the answer is an emphatic yes. The cost of an air purifier is relatively modest compared to medical expenses, missed work or school due to health issues, and the cost of constant cleaning. Most units pay for themselves within months through reduced allergy symptoms and less frequent cleaning.
What Does an Air Purifier Do?
An air purifier removes harmful pollutants and particles from the air inside your room. Specifically, they capture and contain.
- Allergens: Pollen, dust mites, pet dander, mold spores
- Pollutants: Particulate matter (PM2.5, PM10), smoke, ash
- Odors: Cooking smells, pet odors, stale air through activated carbon filtration
- Microscopic threats: Bacteria, viruses, and other airborne particles down to 0.1 microns
Do Air Purifiers Help with Allergies?
Yes, significantly. Air purifiers are specifically designed to capture the airborne allergens that trigger allergic reactions.
Do Air Purifiers Help with mold?
Air purifiers help significantly with airborne mold spores, but here's the important distinction: they prevent mold from spreading through the air but can't remove existing mold from surfaces.
Do Air Purifiers Help Remove Household Smells?
Absolutely. This is where activated carbon filters shine. All Blueair filters include activated carbon, which is extremely effective at removing odors that mechanical HEPA filtration alone cannot capture.
