There are hundreds of air purifiers on the market. Most are fine for normal households. But landfill neighbors need purifiers that excel at two specific things: fine particle capture and meaningful VOC/odor reduction. This guide cuts through the noise.
What We Look For
Our evaluation criteria for landfill-adjacent households: verified CADR (AHAM-tested, not manufacturer claims), genuine activated carbon filtration (volume and weight, not just a carbon pre-filter mat), HEPA or better filtration efficiency, ENERGY STAR certification (running 24/7 matters for electricity cost), and demonstrated reliability.
We do not recommend: ionizers as primary filtration, ozone generators (harmful), ultraviolet-only purifiers (ineffective for particles and limited for VOCs), or units without verifiable performance data.

Ozone generators: harmful to respiratory health. Air purifier claims that emphasize "plasma" or "ion" technology without genuine HEPA: insufficient for PM2.5. Very cheap units under $50: typically have inadequate filtration media and poor sensors.
Carbon Filtration Depth Matters
This can't be overstated for landfill neighbors. A thin carbon mat (common in budget units) adsorbs odor molecules for a few days and saturates. The Winix AOC washable filter, the IQAir V5-Cell, and the Austin Air carbon canisters are genuine carbon stages. When VOC and odor control matter, buy accordingly.
Austin Air HealthMate Plus Junior
15 lbs of activated carbon and zeolite specifically for chemical gas removal. If your primary concern is VOCs rather than particles, this is the purpose-built solution.
