Why Indoor Air Quality Matters
Let's be honest — our indoor spaces don't always feel as fresh as we'd like. Dust, pet dander, smoke, odors, and VOCs from everyday household items can build up over time. Studies show that indoor air can actually carry 2 to 5 times more particles than outdoor air, and since most of us spend about 90% of our time indoors, the air in our homes and workspaces really does matter. The good news? Fresher, cleaner air is within reach.

Triple Filtration Technology
Some air filters rely solely on a single HEPA filter. The UltraLux Air Sentry 500 goes further — combining three filtration stages for a more thorough approach:
- Activated Carbon Filter — helps reduce common household odors and VOCs
- True HEPA 13 Filter — captures 99.97% of particles 0.3 microns or larger
- UV-C Light Component — included as part of the internal filtration chamber design
As an added bonus, we include a True HEPA 14 filter free with your purchase — capturing 99.997% of particles 0.1 microns or larger for even finer filtration.
With the Air Sentry 500, you can capture and reduce:
- VOCs
- PM2.5 particles
- Dust
- Pet dander
- Pollen
- Smoke
- Household odors
This multi-stage system is designed to help your space feel fresher, cleaner, and more comfortable — cycle after cycle.
Long-Lasting Filter Life
The Air Sentry 500 filter is built to last up to 1,500 hours of use — and replacing it couldn't be simpler:
- Turn the unit upside down, rotate, and remove the HEPA filter
- Replace with a new Air Sentry 500 Replacement Filter
- Replace the cover and turn to lock in place
- Enjoy fresher air for another 1,500 hours!
Low EMF Design
Many air purifiers on the market include WiFi connectivity and other features that increase EMF output. At UltraLux Health, we intentionally designed the Air Sentry line without those features. The Air Sentry 500 has an ultra-low EMF rating of just 3 Milligauss at 6 inches on the highest fan speed — so you can enjoy powerful filtration with a minimal EMF footprint.
Choose Your Filter Mode
The Air Sentry 500 offers multiple settings to fit your preferences:
- Automatic / High-Speed — adjust based on your airflow needs
- Sleep Mode — dims the display and lowers noise to a whisper-quiet 30–33 decibels
- Air Quality Indicator — a simple red, yellow, and green light display shows current air quality status in your space
