While I'm not terribly impacted by allergies personally, I've heard this year has been a particularly rough one as spring is hitting. If you're dealing with allergies, you need a powerful air purifier to help you out. Dyson's HEPA filter can remove allergens and pollutants as small as 0.3 microns, automatically filtering the air of 99.97% of those pesky little buggers.

The air purifier also has a layer of activated carbon granules. You can use these to literally capture smells out of the air, which includes anything from a stinky diaper pale to paint fumes. Your air won't just feel clean, it will smell clean. And that's more important than you think.

In addition to purifying your room, the Dyson also acts as a fan. It can heat in the winter and, more importantly given the time of year, cool during the summer. The Air Multiplier tech Dyson's fans are famous for helps project and circulate air up to 400 square feet. You can adjust the projection of the air, too, with either a diffused or focused airflow mode.

If you download the Dyson Link app, you can connect your purifier to it. The machine already automatically monitors, reacts, and purifies the air around it. It can then report to your app and give you the data you need. Remotely control your environment and get it just right. It also has a night-time mode that will use quieter settings, dim the LED display, and use the built-in sleep timer.
