Are you looking for an air cleaner that can help purify the air in your large bedroom or living room? A really good model for this purpose, based on the experiences of users, is the Blue Pure 211+. The price is a little on the expensive side for a purifier in its class. That said, the overall performance, simplicity, size, appearance and energy efficiency make it better than many of its rivaling products in the market. Read more to weigh the pros and cons of this unit.
To start with, the Blue Pure 211+ has a three stage filtering process. There is a colorful washable prefilter to prevent bigger particles reaching the main filter inside and reducing its efficiency. The unit ships with two washable pre-filters. The second stage of filtration is a specially designed particle filter that will capture the small particles like dusts, allergens and other pollutants inside your home. The multiple stages also include a final activated carbon to reduce odors from the air.
The Blue Pure 211+ does not have a true HEPA filter. That said, it outputs HEPA performance. According to the manufacturer, the particle filter is capable of capturing and holding 99% of PM 2.5 airborne pollutants. It is recommended to replace the main filter every six months. However, the actual time frame varies based on a number of variables that include the amount of pollutants in the air, fan speeds and usage. There is an indicator light that will tell you when the main filter needs changing.
The CADR rating of this particular purifier is 350 CFM for smoke, dust, and pollen. It is designed to purify a medium or a large room measuring up to 540 square feet and will manage to produce 5 air changes per hour in that size room. For larger rooms, have a look at the model 121 that offers 620 sq ft area coverage. It offers 400 cubic ft/min Clean Air Delivery Rate (CADR). The model 411 is rated for rooms no larger than 161 square feet.
If you are looking for a feature-packed air filtration system, the Blue Pure 211+ is not the model for you. There are no timer, sensors or other advanced functions. But if you desire a simple unit, then the Blue Pure 211+ is a great choice. It is pretty much pre-assembled out of the box. A touch button on the front of the unit controls three fan speeds. It keeps fan speed setting after power is disconnected. An indicator light lets you know what speed it is running at. The light dims automatically after a few seconds so it would not bother you during the night.
In terms of design, the 211+ comes with a rounded square shape. Measuring 21 X 13 X 13 in, this is a relatively large air purifier. The air intake is 360 degrees so it must be positioned away from walls. A fairly large fan pulls air through the bottom part of the machine. Filtered, clean air blows out of the top part. At 13 lbs, the air cleaner is light enough to move from room to room if needed.
Blue Pure 211+ has received very good feedback from many buyers. Obviously, it is one of the best options for air purifier on the market. Many people have been very happy with the performance. It appears to be effective at filtering out dust, pet dander, and other airborne pollutants. Coming with a carbon filter, people have also found that it really helps with odor removal.
The filter replacement cost is one major drawback of this air purifier. It may not be a dealbreaker for most people, but is definitely a point to consider.Replaceable filter will cost you around $50 every 6 months. Still, the Blue Pure 211+ is inexpensive to maintain. The colored pre-filter is washable. When it comes to energy usage, the Energy Star Certified unit only consumes 65 watts on the highest fan speed (30 watts on the lowest). It uses a 120V power supply to operate. Unlike the 411, it uses a 3-prong plug.
As far as noise goes, people have commented that it is quiet on low speed. Medium and high are louder but even on the highest setting it is less noisy than a regular fan. With a circular shape, the 211+ is a good looking air purifier. Featuring metal cage, it seems sturdy and well made. All Blue Pure units come with a 1-year warranty.
If you want a big, heavy-duty air purifier for heavy allergies or asthma, then this probably is not the right model for you. Alternative products that offer better overall filtration are available out there. The Classic family, for instance, filters 99.97% down to 0.1 microns. That said, If you just need a simple, functional, air cleaner for HEPA filtration around the house, then this product should work for you.
