THE LABORATORY AIR PURIFIER FOR THE AIR YOUR TEAM BREATHES ALL DAY
HALO clears the solvent vapor and the background VOCs that linger in the room long after the work is done. The part of the lab’s air your hood and your ventilation were never meant to catch.
A fume hood captures vapors at the source, and your ventilation moves air through the building. Neither was built to clean the air in the rest of the room, where your team spends the shift breathing whatever drifted off the bench. HALO is a lab air purifier for exactly that air. Ceiling-mounted carbon and HEPA filtration built on more than 50 years of Erlab laboratory work.

The smell you’re nose blind to is still there
Every lab has a smell. Solvents, reagents, the particular note of whatever your group works with. The people who work there stopped consciously noticing it months ago. They are still breathing it.
A fume hood pulls vapor away at the point of use, but plenty still reaches the room. Containers get opened and closed. Samples get transferred. Reagents give off vapor every time they’re handled. Small spills happen. And the general background builds through the day in a way no single hood is positioned to catch. That room air is what your team breathes for eight hours, not the air inside the hood.
Low-level VOC and odor exposure is not just unpleasant. It is the headaches by mid-afternoon, the tired eyes, the scratchy throat at the end of a shift. People put up with it because they always have. They should not have to, and there is a cost to leaving it that way.
HALO works alongside the hoods and ventilation you already have. It does not change how either one operates. It cleans the background air in the room that neither was built to handle.
How the HALO laboratory air purifier works
HALO hangs from the ceiling and connects to building power overhead. No ductwork, no HVAC changes, installed in hours.
Air is drawn upward.
Room air is pulled up into the unit, lifting vapors and particles away from the benches and the breathing zone below.
Lab-grade filtration.
Air passes through Neutrodine activated carbon for VOCs and odors, or HEPA H14 for particles and biologicals, the same filtration Erlab builds into its laboratory equipment.
Clean air returns at the ceiling.
Filtered air rides the ceiling outward and settles back down slowly, keeping the whole room turning over instead of treating one corner.
A Smart-Light ring shows status at a glance, and the IAQ dashboard gives the lab remote monitoring, alerts, and filter detection. Nothing for your team to manage at the bench.
Carbon for the smells, HEPA for the particles
HALO comes in two kinds of filtration. The carbon version adsorbs the VOCs and odors that hang in lab air, the solvent vapor and reagent smell that build through the day. The HEPA version captures particles, including biologicals, at the H14 grade Erlab uses in its laboratory equipment.
Run carbon where the issue is smells and vapors, HEPA where it is particles, or both across a larger space. The carbon is validated to AFNOR NF X 15-211:2009, the strictest molecular filtration standard, and the HEPA to EN 1822:2019, the same standards behind Erlab’s laboratory hoods.
A lab people enjoy working in
Skilled lab staff are hard to find and harder to keep. The work is demanding, and the room it happens in is part of what you are offering. A lab that smells of solvent all day, that sends people home with a headache, is a harder place to stay.
Clearing the air is not a perk on a benefits page. It is part of treating the bench as somewhere worth working, and it is something candidates notice when you are trying to recruit. A room that was obviously thought about says something about how the people in it are treated.
It also takes a recurring complaint off your plate. The smell in the prep room, the haze by the afternoon, the question of why the lab always smells like that. Better to fix the air than to keep fielding it.
How many units does your lab need?
Coverage depends on the room volume and how much filtered air you want on top of your existing ventilation. The HALO carbon model moves about 7,770 cu ft of air per hour. Enter a room below for a quick estimate.

|---|---|---|---|---|
| Prep or small lab (9 ft ceiling) | 300 sq ft | 2,700 cu ft | 4 | 2 units |
| Small lab (9 ft ceiling) | 200 sq ft | 1,800 cu ft | 4 | 1 units |
| Standard lab (9 ft ceiling) | 600 sq ft | 5,400 cu ft | 4 | 3 units |
| Large open lab (9 ft ceiling) | 1,500sq ft | 13,500 cu ft | 3 | 6 units |
A planning estimate for supplemental filtered air, not a replacement for the air changes your lab ventilation provides. Layout, fume hood placement, and bench arrangement all affect the plan, and every order includes a consultation that scopes the real number.
See the difference, don’t just smell it
Erlab AirGradient monitors track VOCs, particulate, CO2, temperature, and humidity in real time, so the improvement shows up as data rather than a vague sense that the room is better. Useful when you want to show your team, your director, or EH&S what changed, and useful for spotting which rooms need attention first.
Step 1
Assess
Put AirGradient monitors in the rooms that bother people most, and see what the air is actually doing through a working day.
Step 2
Address
Place HALO units where the data and the complaints point, ceiling-mounted and always on.
Step 3
Assure
The Indoorcare dashboard tracks it over time, so the before-and-after is your own numbers, not a brochure claim.
What HALO costs to run
| Cost component | HALO laboratory air purifier |
|---|---|
Electricity
|
50W per unit, about $52.60 a year each at $0.12 per kWh, running around the clock. |
|
Filters
|
Filter life depends on the load in your lab, estimated for you up front. Erlab's laboratory carbon averages roughly two years in hood use as a reference point. |
Install
|
Hangs from the ceiling and connects to power overhead. No ductwork, no construction, hours rather than weeks. |
|
Upkeep
|
Out of reach, monitored remotely, with automatic filter detection through eGuard. |
The electricity figure is an illustrative example at $0.12 per kWh. Filter life varies with the load, which is why we estimate it for your specific lab rather than quoting a flat number.
The questions your team will raise
| The concern | The reality | How we help |
|---|---|---|
| We already have fume hoods. | Hoods handle the work at the bench. The room still fills with the background vapor and odor everyone breathes between tasks, and that is what HALO clears. | A walkthrough shows where room-air VOCs and odors build up across the lab. |
| Our techs just put up with the smell. | They should not have to, and the daily experience of the room affects comfort, complaints, and whether people stay. | We start with monitoring so the problem, and the improvement, show up in your own data. |
| Will employees notice the difference? | They notice the smell and the end-of-day headache now. With monitoring you can show the change, and they can feel it. | Before-and-after AirGradient data in the rooms that bother people most. |
| Will EH&S sign off? | HALO is room-air purification that works alongside your existing ventilation and controls, so it sits beside what EH&S already requires. | Documentation on the filtration and monitoring for your EH&S review. |
| What will it cost to run? | 50W per unit, with automatic filter detection so nothing gets missed. | A running-cost estimate built around your lab's hours. |
Frequently asked questions
The basics
What is the best air purifier for a lab?
The best laboratory air purifier is one that handles the VOCs and odors you live with, runs without anyone tending it, and stays out of the way. A consumer box on the bench does none of that well at room scale. HALO uses lab-grade carbon and HEPA filtration, mounts overhead, and runs around the clock without anyone having to manage it.
Will it help with the solvent and reagent smell?
Yes. The carbon version adsorbs the VOCs and odors that build up in lab air through the day. For particles and biologicals, the HEPA version handles those instead. Which one you run depends on whether your issue is smells and vapors or particles, and you can run both across a larger space.
How it fits your lab
Does it work alongside our ventilation and fume hoods?
Yes. HALO supplements the room air on top of your ventilation and hoods. It does not change how either one operates. It cleans the background air in the room that neither was built to handle.
How many units does a lab room need?
It depends on room size, ceiling height, and how much supplemental filtered air you want. As a rough guide, a 600 sq ft lab targeting four supplemental air changes an hour needs about three carbon units. A consultation sets the real number around your layout and bench arrangement.
Can staff switch it off?
No. HALO is mounted overhead and out of reach, so it keeps running rather than getting switched off or unplugged at the bench. Confirm the exact power connection with your Erlab specialist for your facility.
What standards does the filtration meet?
The carbon is validated to AFNOR NF X 15-211:2009, the strictest molecular filtration standard, and the HEPA models meet EN 1822:2019. These are the same filtration standards behind Erlab's laboratory hoods, built up over more than 50 years.
