However formaldehyde and tvoc turn to zero much faster. Hence I now just wait for the HCOH and TVOC to zero. 2.5pm tends to stay on 3-4 whilst calibrating. Initially it read tvocs in two bedrooms (400-480) at almost double the value of the living room but still within acceptable range. However after 15-20 minutes, after measuring some other rooms this could not be reproduced. What strikes me is the HCOH remains low but TVCO is somewhat raised. As with most of these devices one wonders about their accuracy. Are there any regulations regarding their efficacy they should adhere too? ### ⭐ Very bad product, waste of money! *by N***E on 26 April 2019* Terrible! Returning this product as we speak! It did not last for longer than hour when turned on. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/50622840-air-quality-detector-indoor-for-accurate-testing-formaldehyde-hcho-monitor](https://www.desertcart.vn/products/50622840-air-quality-detector-indoor-for-accurate-testing-formaldehyde-hcho-monitor) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-19*
