Key takeaways
- Whole-house purifiers treat air for the entire home through the ductwork.
- They beat portable units for whole-home coverage and convenience.
- Allergy sufferers and smoke-prone areas benefit most.
- They complement, not replace, a good filter.
Portable air purifiers clean one room. A whole-house system cleans every room, quietly, through the ducts you already have. For many Sacramento homes, especially during allergy and fire season, it is a worthwhile upgrade. Here is what to know.
Quick answer
A whole-house air purifier installs in your ductwork and cleans air throughout the entire home, unlike a portable unit that treats one room. It is especially valuable for allergy sufferers and during wildfire smoke. It works alongside a good filter, not instead of one.
What a whole-house purifier does
Installed in the ductwork, it treats all the air your HVAC circulates, capturing or neutralizing fine particles, allergens, and in some systems, odors and microbes, across the whole home rather than a single room.
Whole-house vs portable units
Portable purifiers are fine for one room but you would need many to cover a house, and they take up space and need frequent filter changes. A whole-house system is out of sight and covers everything through the existing ducts.
Who benefits most
- Allergy and asthma sufferers, given our pollen, see our allergy filter guide.
- Homes affected by wildfire smoke.
- Households with pets or anyone sensitive to dust.
It complements your filter
A purifier is not a replacement for a quality filter, the two work together. The filter handles larger particles while the purifier targets the fine ones the filter misses.
