The Blue Pure 311 Auto air purifier is a top pick in Wirecutter's 'The Best Air Purifier 2020' for "Delivering exceptional performance in an attractive form".¹ The Blue Pure 311 Auto take a simple approach to air quality management with an integrated particle sensor, Auto mode setting, and LED air quality display. The ENERGY STAR® certified air purifier delivers high performance with one-button control and customizable pre-filter colors in a lightweight, compact package. Independently evaluated and third-party tested for performance as part of the AHAM Verifide® Program for room air cleaners, this air purifier has a Clean Air Delivery Rate (CADR) of 250 cfm for fine smoke particles, 250 cfm for pollen particles, and 244 cfm for dust particles. Recommended for medium rooms like a master bedroom, living room, or playroom with a 360° air intake to completely filter room air about every 12.5 minutes² (approx. 4.8x an hour at 388 ft²) on the highest speed.³ The 3-step combination particle + carbon filter works with Blueair's HEPASilent™ filtration technology to remove 99.97% of airborne particles down to 0.1 microns, like pollen, dust, pet dander, mold, bacteria, viruses⁴ and more. An additional layer of activated carbon traps light household odors.⁵ Blue Pure 311 Auto quietly cleans the air with less noise than a soft whisper⁶ on low (23 dB) and up to a normal conversation on high (53 dB) – while using less energy than a light bulb (3-35 W) on all speeds.⁷ The one-touch enabled Auto mode is designed to help you maintain a comfortable environment. When enabled, the setting automatically adjusts to real-time conditions reported by the integrated particle sensor. Stay up to date on your air quality with the LED display; it changes color to indicate good, moderate, or poor. Change color in seconds with five fabric pre-filter options inspired by Scandinavian nature. The fabric material of the pre-filter catches larger particles and extends the life of the primary filter. Plus, a hidden compartment in the fabric pre-filter keeps the power cord hidden out of sight. Vacuum the fabric or toss it in the washing machine whenever it needs cleaning. Pre-filter in Arctic Trail (gray) included; Additional colors available for purchase. At Blueair, our Swedish heritage inspires sustainability and quality at the heart of everything we do.

The best just got better with the new Nextbase 622GW 4K Dash Cam. With an abundance of new features and world’s firsts, the 622GW is the most accurate, powerful and highest image quality Dash Cam in the market today. Ultra-clear 4K recording at 30fps captures those all-important finer details, with recording at 1440p HD at 60fps or 1080p HD at 120fps for super slow motion available. An improved sensor ensures enhanced night vision on even the darkest roads. Image quality is at the forefront of the Dash cam revolution, with Image stabilization reducing vibrations from your vehicle and improving footage clarity. Another first for Nextbase is Extreme Weather Mode, to provide a clearer image in misty conditions using special defogging algorithms, crucial for winter and night-time driving. The 622GW is the world’s first Dash Cam to include what3words. This provides your exact location to a 3m square location without the need for a data connection, crucial for emergency services to precisely locate you. Coupled with Emergency SOS and Alexa Built-In, the 622GW shows its further ahead the field with technology advancements. Increased connectivity for transferring footage to your mobile phone is key with new built-in Bluetooth 5.0 and Hyper-Sync Wi-Fi 5GHz speeds are up to 10x faster. This ensures syncing times with the MyNextbase Connect app (IoS 12.1 or later and Android 5.1 and up). The 622GW is compatible with any Nextbase Rear View Module, to offer-all around protection, whilst crucially maintaining front 4K image quality, with 1080p full HD rear recordings. The 622GW features all the much loved Nextbase features including Intelligent Parking Mode, high accuracy 10x GPS readings, a 3” HD IPS touch screen and the fully patented Click&Go PRO mount design, for the ultimate Dash Cam user experience. Note- For this product a U3 class Nextbase microSD card is required (Not included). The ability to maintain a high WRITE speed consistently is what Nextbase SD cards are designed to do better than any other SD card. Any drop/fluctuation in WRITE speed within the SD card causes the Dash Cam footage to buffer, and in some cases will stop the recording entirely. Our Nextbase SD card controller and Firmware on the SD card achieves the requirements from our Dash Cam, where other SD cards cannot. Due to the continuous recording and overwriting of the card, the SD card needs to be a high-endurance card, otherwise the card may develop faults after a period of time; if a lower-capability card is used, certain features on the camera will not fully function due to being unable to re-write and record. Nextbase has over 3 million dash cams sold, 115 unique patents, custom designed processors and improved sensors which record fast moving objects in perfect picture clarity for day and night time driving. Auto adjusts contrast and brightness to further improve the footage details in the event of an accident. Save time, money, and ease with Nextbase Dash Cams.
