Choose an area, compare the options, and build a supply list that fits your space. Bring products from different stores into one simple plan.
01 · Start with your space
Which rooms are you planning for?
Start with one room. Add more to estimate a home-wide budget.
How the sizing estimate works
Each room is sized separately using a planning target of 4.8 air changes per hour (ACH). Units are rounded up using room volume and manufacturer CADR, with the manufacturer’s 4.8-ACH area as a minimum sizing check. A lower fan speed or closed doors changes performance; this is a budget estimate, not a whole-home design.
These figures are for particle filtration. They do not size a gas-removal system. EPA sizing guidance ↗
