X-Sense XR0B-SR radon detector with audible and visual alerts — $53.99 on Amazon, $31.00 off the $84.99 list.
36% offRadon is the invisible one — the EPA recommends testing every home, and this standalone monitor watches it around the clock instead of giving you a one-shot charcoal kit. The XR0B-SR shows a first reading within 24 hours and reaches up to 90% accuracy after 7 days of continuous monitoring, tracks up to 999 days of short- and long-term averages with no lab fees and no subscription, and fires a sound-and-light alert when levels cross the safety threshold. It also displays temperature and humidity — which it uses to sharpen its accuracy — stores up to 99 readings, and runs about 2 years on 3 AA batteries. Amazon has it at $53.99 against the $84.99 list, no code needed, with free shipping.
