Our approach
Read the specs before you buy.
The 2×4 unit has a $1,189.00 listed price before freight, a 24 × 48 in. filter face, and a replaceable HEPA filter. Compare those details with the space you have before choosing a unit.
Leave 4–6 in. behind its intake. Check your bench space and delivery access before ordering a freight shipment.
