Questions from Homeowners
How is Clarity Steadfast different from my charcoal test kit?
A charcoal test kit tells you what radon was doing during one specific week — often years ago. Radon fluctuates constantly with seasons, weather, and ground pressure. A home that reads 1.8 pCi/ L in summer can read 14+ pCi/L in winter. Clarity Steadfast monitors continuously, updating every hour, so you always know what's actually in your home right now — not what was there years ago when conditions were completely different.
Does the level change over time or is one test enough?
Radon levels change constantly. One test is never enough. Continuous monitoring is the only way to actually know what your family is breathing year-round. That's exactly what Clarity Steadfast does — 24 hours a day, every single day, automatically.
Does it need WiFi or an app?
No. Clarity Steadfast has a live digital display that shows you the reading directly on the device. No app required. No WiFi. No phone. No calibration nightmares. It just works — every single hour whether you check it or not. When you walk past it in the morning you see the number. That's it.
What level is dangerous?
The EPA action level is 4 pCi/L — but this was set in 1976 as an economically feasible threshold, not a health-based safe level. The EPA and WHO both state that no safe level of radon exists. At 4 pCi/L, 600,000 radioactive disintegrations are occurring in your lungs every hour. Clarity Steadfast alerts you the moment levels rise to dangerous territory — not after hours or days of exposure.
Where should I place it?
Start with the basement or lowest livable level of your home — this is where radon concentrates first. If you have a ground floor bedroom or a child's room on the first floor, place a second unit there. Most families are fully covered with a 2-pack.
How many do I need?
One for the basement or lowest level. One for the main living and sleeping floor. Most families need a 2-pack. Larger homes or homes where children sleep in basement-adjacent rooms should consider a 4-pack.
Is it hard to install?
No. Plug it into any wall outlet. That's it. 30 seconds. No ladder. No tools. No contractor.
What if it shows a high reading?
Don't panic. Radon is completely fixable. A standard mitigation system — a hole in the slab, a PVC pipe, and a small fan — reduces radon by 80-99% and typically costs $800-2,500. Most installations take 2-3 hours. Thousands of families bring their levels from 20+ pCi/L down to under 1 pCi/L. Knowing is the first step. Steadfast Clarity gives you that.
Can radon be fixed permanently or is it ongoing?
A properly installed mitigation system permanently reduces radon by 80-99%. But you still need continuous monitoring because systems can fail, fans can stop, and conditions can change. Steadfast Clarity is your permanent watchdog — making sure your mitigation system keeps working and your levels stay safe year after year.
What if it doesn't work for me?
You're covered by our 90-Day Sleep In Peace Guarantee. If you're not satisfied for any reason we'll refund every penny. No questions asked. Plus the Lifetime Guarantee means we replace it free if anything ever goes wrong.
How fast will I receive it?
Ships from US warehouse. 3-5 business days typically.
