Why shop here
What this shop is, plainly
Air quality products attract big promises. Here is what we can actually stand behind.
Real-time readings
Both CO2 monitors refresh their reading every second and show carbon dioxide, temperature and humidity on one screen. Open a window and watch the number move.
Manufacturer figures, marked as theirs
Where a maker states a range, an output or a coverage figure, it is on the product page and identified as theirs. We publish no figure we cannot trace.
Monitor and improve, under one roof
A meter to tell you the room is stuffy, an ozone machine for the smell nobody can shift. One range, one delivery.
People who pack the orders
Email reaches the team that picks and packs, seven days a week. No ticket queue, and no script.
Delivery you can check
Free across Canada over $50, Express Delivery at $22 below it or as a paid upgrade, 5 to 7 days after a 24 to 48 hour handling time. Tracking emailed when it ships.
Returns, stated in full
Fifteen days to change your mind under our own policy, and your province's consumer protection legislation if anything is faulty. The returns page says exactly what each costs.
Questions
The things people ask first
Two carbon dioxide monitors (a palm sized meter and a jumbo wall mounted display), two ozone machines for treating odours in an unoccupied room, a UV-C lamp wand, a cordless nano spray gun and a can of recreational oxygen.
How well a room is ventilated. People breathe out carbon dioxide, so in a room with too little fresh air the reading climbs. Outdoor air sits around 400 to 420 ppm; a well ventilated room usually stays under 800; above roughly 1000 to 1500 ppm the room is recycling its own air.
No. It reads carbon dioxide, temperature and humidity only. Fit a carbon monoxide alarm and a smoke alarm separately if you need them.
The listings publish measuring ranges but no accuracy tolerance or calibration figure, so we do not quote one. If you need documented accuracy for compliance, ask us before you order.
No. Ozone is a respiratory irritant. Both ozone machines are used in a space with nobody and no animal in it, and the space is ventilated before anyone goes back in.
Free across Canada on orders over $50. Below that the only option is Express Delivery at $22, which you can also choose on any order as a paid upgrade. Orders arrive in 5 to 7 days after a 24 to 48 hour handling time.

Card payment and PayPal, on a secure checkout. Card details are handled by the payment provider and never reach this website.
Yes, under our own policy: within 15 days of purchase on an unused item in its original packaging, less a $29 packing and handling fee, and you pay return postage. Canada has no general federal cooling-off cooling-off period for an online purchase, so that window is ours. If an item is faulty, your province's consumer protection legislation applies and we pay.
We cover it. Email the team with your order number and a photograph; we pay the return postage and the refund is processed within 24 to 48 hours of the item arriving back.

No. A CO2 monitor is a ventilation gauge, an ozone machine is an odour treatment unit for an empty room, and the UV lamp emits UV-C light. Nothing here raises the humidity of a room. No health outcome, kill rate or filtration standard is claimed for anything on this site.
Yes. Use the wholesale quote page with the quantities you need; schools and offices fitting out several rooms are the usual case.
No. Orders are placed on the website; the call centre number is for questions rather than ordering.
Contact us within 12 hours. Most orders ship within 24 hours, and once packing has started the order can no longer be changed.
Before you buy
What a CO2 reading means, and what it does not
Carbon dioxide indoors is mostly a headcount problem. People breathe it out, and if fresh air is not replacing what is in the room, the level rises. That makes it a good stand in for ventilation, which is otherwise invisible.
The reference points
Outdoor air sits around 400 to 420 ppm, so that is your floor. A room with air genuinely moving through it tends to stay below 800 ppm. Somewhere above 1000 to 1500 ppm you are mostly rebreathing the room's own air. Those are ventilation benchmarks, not health thresholds, and we do not dress them up as anything else.
Watch it change, not just the number
Because the reading updates every second, you can open a window and watch what happens. Some rooms drop hundreds of ppm in a couple of minutes. Others barely move, which tells you the airflow is not where you assumed. That one test is worth more than any absolute reading.
What a CO2 monitor is not
It is a ventilation gauge. It does not detect carbon monoxide, smoke or particulates, and it is not a medical or safety device. If you need a carbon monoxide alarm, fit a proper CO alarm alongside it. The same plainness applies to the rest of the range: an ozone machine treats odours in an empty room and makes no health claim, and a UV-C lamp emits UV-C light and nothing more is claimed for it.
Delivery and returns, in one paragraph

You have 15 days from purchase to change your mind under our own policy, and the returns page states what that costs. A faulty item is covered by your province's consumer protection legislation and costs you nothing.
