CIRS 🙂 A medical necessity  – see purifier recommendations for CIRS in article by Dr Chris Kresser below. These are in line with what my NEM doctor has recommended – her preferred product is Air Oasis
ALLERGIES 🙂  Sensitive Choice recommends, air purifier and dehumidifier   See Dyson and other Purifiers recommended by Sensitive choice  at
LOST Sound Sensitivity!, some may have an odour!
MCS 🙂 A medical necessity! (Dr Ziem) – IQ Air is frequently recommended to people with MCS.  Molekule is the one Dr Gordon likes for sensitive patients at Gordon Medical Associates

Air Purifier

For CIRS Dr Chris Kresser says (source:

Another helpful intervention is to use air filters and purifiers/sanitizers. I will write an article discussing them in more detail soon. For now, I will tell you what I use and recommend to my patients:

  1. A HEPA filter that is capable of removing ultrafine particles (<0.1 microns) like mold, dust, pet dander, VOCs, and even viruses from the air. These ultrafine particles represent 90 percent of all airborne pollution that you breathe.
  2. An air sanitizer that eliminates allergens, odors, mold, and germs.

The number and range of devices on the market in both of these categories is mind-boggling, and I’ve spent countless hours figuring out the best options for our home. My research is ongoing, but currently this is what we are using:

  • An IQAir HealthProPlus. IQAir makes HEPA filters that employ a four-stage filtration process (which includes activated carbon) to filter particles all the way down to 0.003 microns—the smallest particles that exist—with a guaranteed efficacy of more than 99.5 percent. We have one of these in the main living area of our home and one in the basement. Important note: is not an authorized reseller of IQAir, so if you purchase from there the warranty won’t be valid. I recommend purchasing directly from IQAir or from one of their authorized resellers.
  • Blueair Sense filters. Blueair filters use “HEPASilent Technology,” which combines electrostatic and mechanical filtration to capture 99.97% of airborne particles down to 0.1 microns in size. We use these in bedrooms and my home office because they are smaller, quieter, and more energy efficient than the IQAir HealthProPlus units.
  • AirOasis air sanitizers. These units work differently than HEPA filters. They use a technology developed by NASA called advanced hydration photocatalytic oxidation (AHPCO) to destroy mold, bacteria, and other microorganisms with ultraviolet light and a catalyst. We have a few of the Air Angel units in smaller rooms, as well as an AO3000 in the main living area. Important note: I currently recommend running the AO units only when you are not in the rooms, and turning them off when you enter. This is due to the small amounts of ozone that they release. Though these levels are well below the recommended limit according to AO’s website, I prefer to be cautious. I also recommend using a HEPA/charcoal filter along with the AO devices, rather than using them on their own.
