Teendow Air Purifier for Home Large Room up to 3000 Sq.ft, H13 HEPA Filter with PM2.5 Display, Sleep Mode, Timer, Washable Pre-Filter, Aromatherapy

Highlights

• 【Smart Air Quality Sensing & Auto Mode】:This air purifier is equipped with a built-in PM2.5 sensor and a clear LED display that monitors air quality in real time. The screen shows precise PM2.5 values along with color-coded lights (green = good, yellow = moderate, red = poor) so you can instantly understand indoor air conditions. In Auto Mode, the purifier automatically adjusts fan speed based on detected air quality, eliminating guesswork and ensuring a healthier environment without manual settings.
• 【Washable Pre-Filter for Cost Savings】:The reusable pre-filter efficiently captures pet hair, dust, and larger particles before they reach the main filter. Instead of frequent replacements, you can simply remove and wash the pre-filter to keep performance at its best. This reduces long-term costs and helps extend the life of the HEPA filter. By combining convenience with sustainability, it’s a practical choice for households that value both efficiency and savings.
• 【3-Stage H13 True HEPA Filtration System】:Featuring a comprehensive 3-layer design, this purifier includes a washable pre-filter, an H13 true HEPA filter, and an activated carbon layer. Together, they capture 99.97% of airborne particles as small as 0.3 microns, including smoke, dust, pollen, odors, and PM2.5 pollutants. Compared with traditional filters, the advanced H13 filter covers a larger surface area, which significantly boosts purification speed and overall efficiency, giving you fresher, cleaner air throughout your living space.
• 【Whisper-Quiet Sleep Mode for Restful Nights】:Engineered for bedrooms and relaxation areas, this air purifier operates at an ultra-low noise level of just 25dB in Sleep Mode. The gentle operation ensures your rest won’t be disturbed, while all display lights automatically turn off after 10 seconds in Auto Mode for complete darkness. Add a few drops of your favorite essential oil to the built-in aroma pad (not included) to combine purification with calming fragrance, creating a peaceful, restorative sleep environment.
• 【Timer, Safety Lock & Smart Reminders】:Enjoy flexible customization with 1, 2, 4, and 8-hour timer options, plus 4 fan speed settings to adapt purification to your daily needs. A built-in child lock prevents accidental changes by kids or pets, ensuring safe operation. The smart filter replacement indicator flashes red when it’s time to change filters (recommended every 3–6 months), so you’ll never lose track. With its convenient design and thoughtful features, it keeps your air fresh and your household running smoothly.
