Best Air Purifier for Mold

Best Air Purifier for Mold

If you’ve been dealing with allergens before, you know that sealing the leaking windows isn’t going to be enough for breathing more comfortable. Mold, mildew, pet hair, dust, dirt- there are only so many allergens to name that ruin your breathing.

Should you install an air purifier in your home?

There aren’t many medical proofs of how air purifiers alleviate respiratory conditions (caused by allergens, that is). But it’s also true that a good air purifier can make a difference in the air quality inside your home.

The air purifier/air cleaner is a machine capable of removing contaminants from the room, improving the indoor air quality. People struggling with allergies and asthma benefit the air purifiers, which are typically stand-alone units.

For the larger establishments, the air purifiers are larger units and can be attached to the air handler unit.

What makes a good air purifier?

There are myriads of options, and you should know how to make the difference when buying. Even though the budget may be the deal-breaker/sealer for you, you shouldn’t undermine the importance of other aspects such as:

  • Type of filtration

It depends a lot on the quality of the air you currently have in a room and the quality you’re hoping to achieve. Even low-priced models come with HEPA filter (the most effective type of filter when it comes to dust, dirt, mold, and various germs), activated carbon filter. The latter removes smoking, cooking, and unpleasant smells, and pre-filter takes care of big particles and pet hair).

  • Fan

An air purifier uses a fan for sucking in air for filtration. A model without a fan is typically quieter, but it may not perform as well as one with a fan.

  • Servicing indicator

We’re busy all the time, and we don’t want to remember when the filters need changing. Get a model that sends notifications about when it’s time to get new filters/to clean up the filters.

  • Several operating modes

With the quality of air changing throughout the day, you want the air purifier to have several speeds/operating modes. Ideally, you want the machine to identify the quality air automatically and only turn on when the quality isn’t excellent. A dirt sensor on an air purifier adjusts the fan speed, helping the machine to become also an energy saver.

  • Ionizer

A unit that comes with ionizer (it collects particles due to static electricity) isn’t going to produce ozone. If you don’t know, ozone is irritating for the lungs.

  • Programmable timer

It’s a great feature to have on the air purifier since it lets you set the machine to run for a couple of hours before you enter a room.

  • Washable pre-filter

Reusable and easy to wash pre-filters are excellent, as they collect large particles and cut down the spending in the long run. Keep in mind that it’s not a standard feature for the highly-rated models. At least, the filters should be easy to remove for replacing.

One last tip before you go shopping

The more you play, the more you should expect in terms of power, efficiency, level of noise, and durability. Extra-features always count (a carry handle may be the selling point for some), which is why you should make time selecting wisely.
