  • Power: Battery: Recharges in 3.5 hours, with over 1 month of continuous monitoring; capacity not stated on AEGTEST's current store

The HOUND-1085 is a palm-sized, rechargeable radon detector from AEGTEST: a semiconductor sensor behind a triple-vent design, a first reading after 6 hours and hourly updates after that, color-coded bars with sound alerts, and up to 504 days of history on the device. AEGTEST's earlier store listed a range of 0.09 to 1500 pCi/L and an accuracy of ±15%; AEGTEST posts no manual online, and the HOUND-1085 was not included in C-NRPP's 2024/25 consumer monitor evaluation.

What you get

AEGTEST lists one HOUND-1085 radon detector, a charging data cable and a user manual, ready to use out of the box. The manual is in the box only: AEGTEST posts no copy online, and the general help page of its earlier store answered the question of where to find the instruction guide by asking buyers to contact the company. AEGTEST sells the HOUND-1085 under two listings on its own store, one of them in grey.

How it works

In our words, from the maker's documents

AEGTEST says the HOUND-1085 integrates a high-accuracy semiconductor radon sensor with a triple-vent design to accelerate radon diffusion: air reaches the sensor on its own through the vents, and AEGTEST names no pump. The FAQ on its earlier store's HOUND-1085 page gave AEGTEST's account of how its detectors measure: the sensor counts the alpha particles of radon in each sample of air it analyzes, works continuously, and every hour produces a data point that contributes to an average reading, which is why the readings show as averages over 24, 48 and 96 hours.

The first reading appears after 6 hours, AEGTEST says, and then updates automatically every hour. The device logs a value every 6 hours and keeps a history of up to 504 days, with short-term views of the past 6, 24, 48 and 96 hours, all shown on the device itself. AEGTEST's description mentions no app, Wi-Fi or Bluetooth.

AEGTEST's current product page gives no measurement range or accuracy. The specification table on its earlier online store listed a reaction range of 0.09 to 1500 pCi/L, an accuracy of ±15%, a first display after the device has worked for 6 hours, and operating conditions of 14° to 113°F, with the humidity value missing from the row. The table gives no radon level or test period for the ±15%, and no AEGTEST page says whether the HOUND-1085 can show Bq/m³, so that option is not stated by the maker.

Power is a rechargeable battery: AEGTEST says it recharges in 3.5 hours and gives over 1 month of continuous monitoring. The earlier store's table listed it as a 2500mAh, 3.7 V lithium battery, beside a weight of 0.27 lbs, and the earlier store put its runtime at up to 45 days in ECO mode. Neither store names the charging port.

For warnings, AEGTEST describes color-coded bars that indicate radon levels, paired with customizable sound alerts that warn of elevated concentrations. It does not say what level sets the sound off, or whether customizable means the level, the volume or both, so the alarm level is not stated by the maker.

Recalls
No Health Canada recall or advisory names this device.
Peer-reviewed studies
We found no peer-reviewed comparison that names this model.
Notes
  • No Health Canada recall or advisory and no CPSC recall names AEGTEST or a HOUND device, and C-NRPP's consumer monitor page lists none, approved or not approved (checked 2026-10-08).

What is in the box

AEGTEST lists one HOUND-1085 radon detector, a charging data cable and a user manual, ready to use out of the box. The manual is in the box only: AEGTEST posts no copy online, and the general help page of its earlier store answered the question of where to find the instruction guide by asking buyers to contact the company. AEGTEST sells the HOUND-1085 under two listings on its own store, one of them in grey.

AEGTEST's warranty page, which covers its store as a whole, promises a three-year warranty, described as a 36-month after-sales service with lifetime technical support. It excludes faults caused by unauthorized disassembly, damage from water or strong mechanical force, and normal wear that does not affect function, says AEGTEST is not responsible for loss of use or incidental damages, and points buyers to AEGTEST's support email for warranty help or repair.

What it costs to run

There is no lab fee and no battery to buy: the 2500mAh lithium battery the earlier store listed is recharged with the cable in the box, in 3.5 hours by AEGTEST's figure. AEGTEST mentions no app, subscription or cloud service for the HOUND-1085, and it publishes no sensor life, recalibration interval or service schedule.

Fit and setup

Who it fits, and how to use it

The fit, then setup and placement as the guidance asks

Who it fits

Good fit if, and look elsewhere if

Good fit if

  • You want a palm-sized detector to move from room to room around the home.
  • You want readings and up to 504 days of history on the device itself, with no app or account.
  • You want a rechargeable battery that runs for weeks between charges.
  • You want a warranty term longer than one year.

Look elsewhere if

  • You want a manual or a current specification sheet you can read before buying; AEGTEST posts neither for the HOUND-1085.
  • You want a first number within minutes; the first reading takes 6 hours.
  • You want a monitor that has been through C-NRPP's evaluation; the HOUND-1085 was not included in its 2024/25 round.
  • You need a result for a home sale; check what your state accepts before relying on any consumer detector.

Setup and placement

4 steps

  1. AEGTEST's earlier store gave its own testing advice with the HOUND-1085: keep doors and windows closed during testing, while still going in and out of the home; place the detector at least 36 inches from the floor and 12 inches from exterior walls and frequently used doors; test in the room above or beside a crawl space rather than in it; and avoid testing during heavy rainstorms. The same FAQ recommended letting the detector measure for at least 3 to 7 days so that it collects enough air samples for a reliable average.
  2. The EPA's guidance for any home radon test adds a time: for a short-term test lasting just 2 or 3 days, close your windows and outside doors at least 12 hours before beginning the test. It puts the test at least 20 inches above the floor, which the earlier store's 36 inches clears, on the lowest lived-in level of the home, in a room used regularly but not the kitchen or bathroom, and away from drafts, high heat, high humidity and exterior walls.
  3. The FAQ on the HOUND-1085's page of AEGTEST's earlier store adds three cautions. Keep humidity below 90%, with a dehumidifier, an air conditioner or granular desiccants near the air inlets on the sides or bottom of the device. Keep it out of strong light such as sunlight or a camera flash; the device has a built-in light-blocking film, but that FAQ still advises against direct exposure. And expect a high reading at startup, because the unit is exposed to radon during final factory testing: blow air across the inlet with a fan for a few minutes, then restart the measurement and wait 6 hours for the first reading.
  4. For a decision about fixing your home, C-NRPP's advice for any consumer monitor is to place it in a room occupied at least 4 hours a day, test for a minimum of 3 months, preferably in the heating season, and decide on the long-term average, with a follow-up long-term test if you have less than 91 days of data. The EPA's guidance is to fix a home at 4 pCi/L or more and to consider fixing between 2 and 4 pCi/L.

How C-NRPP says to use any consumer monitor

  • Leave it in place for at least three months, ideally through the heating season, when indoor radon tends to be highest.
  • Put it in a room someone uses for at least four hours a day.
  • Decide about fixing your home from the long-term average, not a single day or week.
  • If you can only run a monitor for less than 91 days, follow up with a long-term test.

Questions

Questions people ask

6 questions about the AEGTEST HOUND-1085, answered

Asked about the HOUND-1085

Who makes the HOUND-1085?

AEGTEST, which sells it on its own online store. The store's own record gives Shenzhen, Guangdong, China as its location and prices in US dollars, and lists the United States among the countries it ships to. The AEGTEST trademark is registered in the US to Shenzhen Xunyi Electronic Commerce Co., Ltd., with radon detectors among the goods it covers.

How accurate does AEGTEST say the HOUND-1085 is?

AEGTEST's earlier store listed ±15% in its specification table, with no radon level or test period attached; its current page calls the sensor high-accuracy without a figure.

There is no independent result to compare it with: the HOUND-1085 was not included in C-NRPP's 2024/25 consumer monitor evaluation. That is not a failed test; it means no independent result exists.

Why is the reading high when I first switch it on?

The FAQ on AEGTEST's earlier store page for the HOUND-1085 says the device is exposed to radon during final factory testing, so first readings may be high. Its fix is to blow air across the inlet with a fan for a few minutes to clear the residual radon, then restart the measurement. AEGTEST's current store does not raise the point.

Why is there no number on the screen after a restart?

The FAQ on AEGTEST's earlier store page for the HOUND-1085 says that after a restart or the Retest function, the measurement screen resets while the history is kept, and to wait 6 hours for the first reading to appear.

Does humidity or light affect it?

The FAQ on AEGTEST's earlier store page for the HOUND-1085 says both can. It advised keeping humidity below 90% and keeping the detector out of strong light such as sunlight or a camera flash; if it has been exposed, put it somewhere dark, such as a drawer, and wait before measuring again. AEGTEST's current store does not mention humidity or light for the HOUND-1085.

How long should I leave it running?

The FAQ on AEGTEST's earlier store page for the HOUND-1085 recommended at least 3 to 7 days, and said that after one month a detector has probably gathered enough data to start showing a pattern, with the average settling on a reference level. For a decision about fixing a home, C-NRPP's advice for any consumer monitor is a minimum of 3 months, preferably in the heating season.
