🔬 What Makes the Sans Air Purifier Different?
The Sans air purifier entered a crowded market in 2020 with a clear mission: deliver medical-grade air purification that’s accessible, affordable, and actually effective. Here’s what sets it apart:
🏥 Medical-Grade HEPA 13 Filtration (Not Just “True HEPA”)
Most consumer air purifiers use “True HEPA” or HEPA-type filters, which capture 99.97% of particles at 0.3 microns. The Sans uses a HEPA 13 filter, which captures:
| Particle Size | Capture Rate | What This Means |
|---|---|---|
| 0.3 microns | 99.97% | Standard HEPA performance |
| 0.1 microns | 99.95% | Captures viruses, ultrafine smoke |
💡 Why This Matters: HEPA 13 filters are used in hospitals, clean rooms, and medical facilities because they capture particles smaller than viruses and bacteria—protection that standard “True HEPA” filters can’t match.
⚡ 4-Stage Filtration System with UV-C Sterilization
1️⃣ Pre-Filter
Captures visible contaminants like pet hair, dust, and lint. Washable and reusable.
2️⃣ HEPA 13 Filter
Traps microscopic particles including allergens, mold spores, bacteria, and viruses down to 0.1 microns.
3️⃣ Activated Carbon (1 lb)
Absorbs odors, VOCs, gases, and harmful chemicals from cooking, pets, and cleaning products.
4️⃣ UV-C Light
Provides germicidal protection by deactivating airborne pathogens. CARB-certified, 100% ozone-free.

❓ Frequently Asked Questions About the Sans Air Purifier
Is the Sans air purifier worth it for allergies?
Yes, absolutely. The Sans is particularly effective for allergy relief thanks to its medical-grade HEPA 13 filtration. Multiple users report noticeable reduction in seasonal allergy symptoms, sinus congestion, and respiratory irritation within 3-5 days of use. The combination of HEPA filtration for particles and activated carbon for chemical irritants provides comprehensive protection against pollen, dust mites, mold spores, and pet dander.
How loud is the Sans air purifier?
At low and medium speeds, the Sans is exceptionally quiet (25-42 dB)—quiet enough for bedrooms, nurseries, and home offices without disrupting sleep or Zoom calls. High speed produces moderate noise (50-55 dB), similar to a quiet conversation, but the auto mode intelligently limits high-speed operation to brief periods when air quality dips.
Does the Sans air purifier remove odors?
Yes. The Sans includes 1 pound of activated carbon specifically designed to absorb odors, VOCs, gases, and harmful chemicals. Users successfully report elimination of cooking odors (bacon, fish, spices), pet smells, smoke, and chemical odors from cleaning products and paint.
How often do Sans filters need replacement?
Sans recommends replacing filters every 3 months (approximately 2,200 hours of continuous use). The unit includes a filter replacement indicator that blinks red when it’s time to change. While this is more frequent than some competitors, the lower filter cost ($35.99 with subscription) helps balance the total ownership cost.
Is the UV-C light safe?
Yes, completely safe. The UV-C light in the Sans is fully enclosed within the unit, preventing direct exposure to skin or eyes. It’s CARB-certified to be 100% ozone-free, meaning it won’t produce harmful ozone as a byproduct. The UV-C light safely deactivates airborne pathogens (bacteria, viruses, mold) that pass through the filter chamber.
Does Sans work for wildfire smoke?
Yes, very effectively. The HEPA 13 filter is highly effective at capturing fine particulate matter from wildfire smoke (PM2.5 and even smaller PM1 particles), while the activated carbon layer absorbs smoke odors and volatile organic compounds. For comprehensive wildfire smoke protection, run the Sans in auto or high mode during smoke events.
