Best home air purifier for health, Which one should I buy?

#1

Hello everyone on this forum,

I have been reading a lot about longevity, healthy aging and ways to improve overall health span. We often discuss nutrition, exercise, sleep, supplements and medications but one factor that seems to get less attention is indoor air quality.

Many doctors and health experts emphasize that taking care of your health today can help you enjoy a longer and healthier life in the future. While there is no single longevity hack, reducing exposure to airborne pollutants, dust, smoke, allergens and other particles may help support respiratory health and overall well-being.

Considering that most people spend a significant amount of time indoors, using one of the best air purifiers for home use could be a worthwhile investment. Cleaner indoor air may help reduce exposure to pollutants that can contribute to inflammation, allergies, and other health concerns.

I’m curious about the community’s experience:

  • What do you consider the best air purifier for home use?
  • Have you noticed improvements in sleep, allergies, breathing, or general health after using an air purifier?
  • Do you think indoor air quality is an underrated factor when it comes to longevity and healthspan?

I do love to hear recommendations, personal experiences and any research related to air purification and long-term health.

I have thought about this a bit, so I got an Air Purifier. It’s called a ProBreeze, and I got it because it was supposed to be quiet.

On its lowest setting it is. Haven’t perceive much difference, but indoor air pollution is not something you would notice. I used to put it on in morning and evening but haven’t done that recently, just through laziness. I just touched up some paintwork so I you have reminded me to put it on!! :smile:

We have 1 in each bedroom and run 24/7. Not sure brand matters much.

I recommend The Wirecutter’s review: https://www.nytimes.com/wirecutter/reviews/best-air-purifier/.

In fact, I have recommend and used The Wirecutter as my primary resource to answer the question “What’s the best X?” for most things for perhaps over a decade, since well before they were acquired by the NYT.

I bought the air purifier that has been their “best” pick for a long time, the Coway Airmega Mighty, on their recommendation and have been happy with it in my ~10 years of ownership.

I see that there’s now a newer version of that product and that it’s their current top pick.

I have a HEPA filter in my bedroom on automatic at all times. A LOT of dust is filtered by it. It doesn’t replace cleaning, but any time I’m cleaning my bedroom dust is thrown in the air, so I turn it on to maximum setting for an hour or 2 after cleaning then back to automatic.

I use Winix brand, but that doesn’t mean it is the best.

We just have the Dyson (https://www.dyson.co.uk/air-treatment/purifiers/purifier-cool-pc1/white) ones. They look cool, they have proper HEPA filters, and they double up as a fan to circulate air around the room. There is also a new “Hushjet” product which is only a purifier. All the Dyson’s have the HEPA filter, a carbon filter, and can remove formaldehyde (from paint, glues, certain woods etc - very relevant if you move into a new house or have work done).

What I like is that they show you the various levels of pollutants (VOCs, NO2, PM2.5, PM10) live on the screen. As a general threshold you want your PM2.5 to be less than 5µg/m^3. Without the purifier, ours often drifts to 10-15, which is not terrible, but isn’t optimal. However, with the purifier running, it quickly goes down to 1-2µg/m^3.

It also kicks off when you spray perfumes, use the stove etc, and quickly brings those VOC levels down to normal.

Our house has 4 of them in total. One in the major living area, and one in each of the bedrooms. They run 24/7 on auto mode, so they spin up or down depending on pollution levels. The logic is that if you spend 8h per day in your bedroom, and you can reduce your PM2.5 exposure during sleep, that’s a significant benefit overall.

The Dysons are fairly pricey, and I think the HEPA filtration part is a pretty basic technology. I’m sure the Coway, Honeywell, and even IKEA ones will do the job of pushing air through a filter just fine.

And as AustraliaLongevity says, it will suck up dust, but it’s no substitute for running a vacuum cleaner. If you have allergies (dust, pollen, animals), or overt pollution (fires etc) then regular vacuuming is going to be super important.

The “best” is the one with hepa filter. I have three Winix Plasmawave purifiers from Costco. They work very well and filter a lot of dust. Run them 24/7.

Hi, I think you’re absolutely right that indoor air quality is often overlooked when talking about long-term health and healthy aging. Taking care of your health with the right devices can help you live a happier and more enjoyable life.

I have been using the PuroAir air purifier for a while now, and it has worked very well for me. It uses a high efficiency HEPA filtration system that helps remove dust, pollen, pet dander, smoke particles, and other airborne pollutants. One thing I like is that it’s quiet, energy-efficient, and effective at improving air quality throughout the room.

Since using it, I have noticed less dust in my home and fresher air overall. While an air purifier isn’t a magic solution for longevity, I do think cleaner indoor air can support better respiratory health, improved sleep quality, and overall well-being.

I’d be interested to hear what other air purifiers people here are using and how their experiences compare.

I have several Winix smaller (~2’x3’) brand air purifiers at our home in Arizona. I have been happy with them. I purchased them at Costco and they came with extra filter kits. If you keep the pre-filter screen and the carbon mesh secondary filter clean (easy to do), the main HEPA will last a long time.

At our home in Idaho, I purchased (also at Costco) two larger Shark 5-year systems. I like them equally well. In theory, the HEPA system will do its job for five years of normal use. Large forest fires are possible in the late summer and early fall in the northwest so I will be pleased if these filters hold up for three years.

Both brands are reasonably quiet with a slight nod to the Shark.

The Shark I mentioned is on sale at Costco and the filter life has been extended to six years. This is a relatively large machine.

Hello, you make a great point. I also believe that improving indoor and outdoor air quality is one of the simpler lifestyle changes that can support long term health.

Over the years, I have tried several devices focused on creating a healthier home environment and air purifiers have made one of the most noticeable differences especially for dust, seasonal allergies, and overall air freshness.

Two models that have worked well for me are:

BLUEAIR Air Purifiers for Large Rooms (Blue Pure 211i Max)

https://www.amazon.com/BLUEAIR-Purifiers-HEPASilent-Allergies-Purifier/dp/B0BN2MGV5H/

Great coverage for larger spaces and very effective at reducing dust and airborne particles.

PuroAir 240 HEPA Air Purifier

https://www.amazon.com/PuroAir-Air-Purifier-Bedroom-Allergens/dp/B0998FWTHP/?th=1

Covers up to 1,000 sq ft and does a good job filtering smoke, pollen, dust, and other common indoor pollutants while remaining relatively quiet.

While an air purifier isn’t a magic solution for longevity, I think it complements other healthy habits such as exercise,smoke and carbon monoxide detector, quality sleep, good nutrition, and regular health checkups. Small improvements in the environment we live in every day can add up over time.

IQ Air Hepa Pro (or their HVAC filter system) is industry standard and doesn’t ionize the air like most do today (a questionable idea and one that causes issues in more sensitive people). But it’s not that small or attractive, and it’s important to keep getting their hyper hepa filters (that grab exponentially smaller molecules) instead of OEM replacements. So it’s also pricey. But for those with severe allergies, even to indoor air, it tends to be the standard.

Basically it comes down to your needs, aims, price point for ongoing filter replacements, and aesthetics, as there are many OKAY purifiers out there.

But um, Austin Air Purifier (with permanganate) for formaldehyde and VOCs [there’s a study using THAT to reduce highway-adjacent Somerville air pollution by levels enough to improve cognition], and the hospital-grade IQAir…

I prefer an air purifier that is standalone with a pre-filter screen I can clean and a HEPA filter. The pre-filter doubles the useful life of your HEPA filter and is easy to clean.
