Tips for cleaner air at home:


In addition to the tech tools mentioned above that help cleanse indoor air, there are other low and non-techichal ways you can live in cleaner, healthier air.

  • Add indoor plants: While being easy on the eyes, indoor greenery can reduce carbon dioxide in the air. Specific plant species can also reduce airborne chemicals.
  • Let fresh air in: Growing up in northern New England; we always looked forward to the day in spring when we could open the windows and let in the fresh air. Stagnant indoor air can smell bad, feel bad, and make you feel overly tired.
  • Avoid harsh cleaning chemicals: Choose your home cleaning supplies carefully. Some materials are excellent cleaners but not so good for humans’ breathing. Check the labels.
  • Cooking odors — don’t burn your food: Even perfectly cooked food can produce lingering odors, but the smell of burnt food or smokey cooking oil can last a long time.
  • Leave your shoes by the door: Let’s not even think about the number and variety of chemicals, dirt, debris, and organic matter we bring into our homes on our shoes. If we routinely leave our footwear by the door (preferably in the garage, all that nastiness stays outside.
  • Humidity control: If indoor air is too dry, your eyes may itch, and your throat and nasal passages can get sore and vulnerable. If the air is too humid, mold and mildew proliferate. You don’t need a humidifier to add moisture, just put a few moist towels around the house. Fans, air conditioners, dehumidifiers, and sometimes the open window trick can help reduce humidity.
  • Dust your dust: Keeping your home vacuumed, dusted, and clean overall lessens the buildup of unpleasant or even harmful substances, many of which release unwelcome molecules into the air.
  • Minimize pet dander and hair: Furbabies are lovely in many ways, but even non-shedding dogs drop hair in your home — just like people do. If you can keep your pets groomed and clean the floors, mainly but also upholstered furniture, you can cut down on allergens and that less-than-pleasant doggy smell.
  • Let your vacuum cleaners help with air-cleansing: Many vacuum cleaners, including robots, canisters, sticks, and upright styles, are available with HEPA air filtration. Air-purifying vacuums often cost a bit more than models without filtration, but the extra expense pays back with cleaner air. Some pet vacuums are particularly good at picking up dog and cat hair.

Best Prime Day air purifier deals 2021: What to expect

It's hard to believe, but the Prime Day 2021 date is set on June 21 and 22, which is already next week. Since Amazon's annual two-day blowout was delayed until October in 2020, the 2021 Prime Day deals are rolling in less than a year after the last sale, giving shoppers the chance to score all sorts of goodies at the lowest prices you're likely to see before Black Friday. If you're looking to freshen up your home for the summer, here are the Prime Day air purifier deals we're looking forward to, along with some expert tips on how to shop the sale.
What Prime Day air purifier deals to expect
Air purifiers go on sale fairly often and they're a particularly hot item during the spring and summer for reasons that should be fairly obvious. Prime Day also offers discounts on pretty much every type of item that Amazon carries, but especially for pricey electronics, and air purifiers tick both of those boxes. In short, you can expect to see a lot of Prime Day air purifier deals this summer from top brands like Rabbit Air, LG, Winix, Honeywell, and Germ Guardian, to name just a handful of the top makers that get marked down during sales like this.
What Prime Day air purifier deals we saw last year
To get an idea of what specific Prime Day air purifier deals we're most likely to see this year, all we have to do is rewind the clock a bit to the 2020 offerings. Last October, some popular picks included the Rabbit Air MinusA2, the Winix 5300 and 5500 models, the Bissel MyAir compact purifier, and much of the excellent Germ Guardian lineup. The innovative Dyson Pure series also saw some nice price cuts, which were particularly welcome since these cutting-edge air purifiers cleave to the more expensive end of the spectrum.

Not all of these Prime Day air purifier deals were on Amazon, either; plenty of other retailers including Walmart and Best Buy ran sales concurrent with Prime Day and this year will be no exception. That's good news for shoppers who don't have Amazon Prime and can't take advantage of the member-exclusive Prime Day Lightning Deals.
