Best Plants for the Office to Keep Air Clean & Fresh: NASA Clean Air Guide for Workplaces
Adding greenery to a workplace is one of the least expensive upgrades a business can make, and it pays off in comfort, mood, and the way a space feels. In Ottawa, where buildings stay sealed for months each winter, a handful of well-chosen plants can help offset dry air and stale air circulation. This guide walks through the science, the best species for office conditions, and the simple care routine that keeps them looking their best, whether your office is in a downtown tower or a Kanata tech park.
Quick Summary
Indoor plants add humidity, soften a room and make an office feel calmer. They do not replace ventilation or cleaning as an air-quality measure. This guide covers the best low-maintenance plants for Ottawa offices, what they realistically do, and how to care for them alongside a professional cleaning routine.

The Science of Phytoremediation: How Office Plants Filter Indoor Air
Ottawa office buildings remain tightly sealed for a large part of the year. Synthetic carpet adhesives, printer toners, particleboard desks, and wall paints continuously emit volatile organic compounds (VOCs) into recirculated HVAC air, and those compounds build up when fresh air intake is low.
It is worth keeping the mechanical measures in view alongside the biological ones. Health Canada's guidance on fine particulate matter lists cleaning with a mop, a damp cloth or a HEPA vacuum first among the ways to reduce indoor exposure. Health Canada also notes a limit worth knowing: “Outdoor particulate matter levels may often be higher than indoor levels.”
NASA's Clean Air Study showed that certain plant species absorb gaseous compounds through their leaves, and that soil microbes around the roots break some of those molecules down. That work was done in small sealed chambers, and later building-science research found the effect is negligible at office scale: ventilation moves far more air than any realistic number of pots. Adding greenery to workspaces across Ottawa, from open-plan offices in Kanata to executive suites downtown, is worth doing for humidity, comfort and how the room feels, not as an air-filtration measure.
Top Low-Maintenance Plants for Ottawa Office Workspaces
Select these low-maintenance, shade-tolerant species for a workspace. Each one tolerates the fluorescent lighting and occasional missed watering that are common in real offices:
| Plant | Care & behaviour | Air-quality benefit |
|---|---|---|
| 1.Snake Plant (Sansevieria trifasciata / Mother-in-Law's Tongue) | Virtually indestructible in low-light office corners. | It converts carbon dioxide to oxygen at night and is known for filtering formaldehyde, xylene, and toluene. |
| 2.ZZ Plant (Zamioculcas zamiifolia) | Thrives under fluorescent office lighting with minimal watering. | It absorbs airborne volatile organic compounds and features high-gloss dark green leaves that tolerate neglect. |
| 3.Golden Pothos (Epipremnum aureum / Devil's Ivy) | A fast-growing vining plant ideal for high filing cabinets or hanging planters. | It is known for removing formaldehyde, benzene, and carbon monoxide. |
| 4.Peace Lily (Spathiphyllum) | A flowering plant that helps neutralize airborne ammonia, benzene, and trichloroethylene. It also increases indoor humidity levels in dry winter offices, but keep it out of reach of pets. | |
| 5.Spider Plant (Chlorophytum comosum) | It produces baby plants that make easy office giveaways. | A resilient, pet-safe desktop plant that filters xylene, formaldehyde, and carbon monoxide. |
| 6.Rubber Tree (Ficus elastica) | A large-leaf plant that acts as a natural air filter and dust magnet, helping remove airborne particulates in high-traffic office reception lobbies. | |

These plants were chosen for a reason: they tolerate the low light and irregular watering that come with office life. Start with two or three, see which ones thrive in your particular corners, and let your collection grow from there.
Psychological Benefits & Biophilic Workplace Design
In addition to bio-filtering airborne pollutants, indoor plants provide real cognitive and emotional benefits for corporate teams across Ontario:
Stress Reduction & Calmer Focus:
Exposure to natural foliage in office environments reduces psychological stress, lowers blood pressure, and supports a calmer, more focused workday.
Noise Damping in Open-Plan Workspaces:
Dense leaf canopies absorb and scatter high-frequency background acoustic noise, creating a quieter environment in open-plan tech workspaces.
These benefits are especially noticeable in call centre cleaning for high-density workspaces, where noise and constant foot traffic already put extra strain on a room's air and acoustics.
Formatted Step-by-Step Office Plant Care & Cleaning Checklist
Follow this checklist to keep office plants healthy and your workspace clean:
- Step 1.Choose Easy, Shade-Tolerant Varieties for Each Zone:Match plants to the light in each corner so they thrive without constant attention.
- Step 2.Water on a Schedule That Suits the Plant:Most office plants prefer to dry out slightly between waterings; overwatering is the most common mistake.
- Step 3.Dust Leaves Monthly With a Damp Microfibre Cloth:Clean leaves absorb more light and filter air more effectively.
- Step 4.Use Saucers or Trays to Protect Desks and Floors:Catch overflow so water never stains furniture or carpets.
- Step 5.Trim Dead Leaves and Refresh Soil Seasonally:A quick trim keeps plants tidy and prevents mould on spent foliage.
- Step 6.Contracting professional commercial office cleaning services in Ottawa through Good Cleaner Co. keeps plant-friendly dusting and HEPA vacuuming on a consistent schedule.
Maintenance Guidelines: Keeping Office Foliage Clean & Free of Dust
Plants cannot filter air efficiently if their leaf pores are blocked by accumulated office dust. Pairing plant care with a few easy hacks for a sparkling clean office keeps both the greenery and the desks looking their best:
Bi-Weekly Leaf Wipe-Down:
Dust buildup on large-leaf plants like Rubber Trees and Peace Lilies blocks sunlight and reduces their filtering ability. Janitorial teams gently wipe leaves with damp microfibre cloths.
Soil Moisture Management & Mould Prevention:
Overwatering office plants creates stagnant soil moisture, inviting fungus gnats and mould spores. Use well-draining pots with saucer trays.
Choosing the Right Plant for Your Office Space
Compare lighting, watering, and filtration strengths across top office plant choices:
| Plant | Light Level | Water Frequency | Key Toxins Filtered | Maintenance Score |
|---|---|---|---|---|
| Snake Plant | Low to Fluorescent | Every 3-4 Weeks | Formaldehyde, Xylene, Nighttime O2 | 5/5 (Easiest) |
| ZZ Plant | Low to Medium | Every 3 Weeks | Benzene, Toluene, Heavy VOCs | 5/5 (Easiest) |
| Golden Pothos | Low to Bright Indirect | Every 1-2 Weeks | Formaldehyde, Carbon Monoxide | 4.5/5 (Easy) |
| Peace Lily | Medium to Low | Weekly (Moist Soil) | Ammonia, Trichloroethylene | 3.5/5 (Moderate) |
| Rubber Tree | Bright Indirect | Every 1-2 Weeks | Airborne Particulates, VOCs | 4/5 (Easy) |
How Many Plants Does an Office Really Need
There is no single magic number, but a practical rule of thumb is one medium plant per 100 square feet of floor space, with extras near printers, kitchens, and meeting rooms where pollutants concentrate. More important than the count is the care: a few healthy, well-dusted plants do more for an office than a dozen neglected ones. Build the routine first, then add greenery as the maintenance becomes second nature.
- Start small: Begin with two or three easy varieties in the areas people use most, then add more as the routine becomes habit.
- Group plants near light sources: Offices with limited natural light do better with plants clustered near windows or under bright fixtures.
- Match the plant to the space: Tall, broad-leaf plants suit lobby corners, while compact plants work on desks and shelves.
Caring for Office Plants Through the Ottawa Seasons
Ottawa's seasons change how an office building feels, and plants respond to those shifts. A little seasonal awareness keeps office greenery healthy all year.
Winter
Heating systems dry out indoor air, so plants may need a little more water and an occasional misting. Move sensitive plants away from radiators and cold windows.
Spring
As daylight returns, plants start growing again. This is a good time to repot anything root-bound and refresh the top layer of soil.
Summer
Air conditioning can chill plants near vents, so check that watering keeps pace with warmer temperatures and brighter light.
Fall
Reduce watering as growth slows, and bring any plants that spent the summer outside back in before the first frost.

FAQ
Do office plants really improve indoor air quality?
Not measurably, on the air-chemistry side. NASA's sealed-chamber research showed plants absorb VOCs like formaldehyde and benzene through their leaves and roots, but at office scale the effect is swamped by ventilation, and building-science studies since have found the contribution negligible. What plants do reliably deliver is moisture that eases winter dry air, and a room people prefer to work in. Treat them as comfort, and rely on ventilation and cleaning for air quality.
Which plant is best for windowless office cubicles in Ottawa?
Snake Plants and ZZ Plants thrive under standard fluorescent or LED ceiling lights with minimal sunlight, making them ideal for interior cubicles and basement offices.
How many plants are needed per square foot of office space?
A reasonable starting point is one medium-sized plant per 100 square feet of office space, with a few extra placed near high-traffic areas and printers where VOC levels tend to be higher.
Are Peace Lilies safe for pet-friendly offices in Ottawa?
Peace Lilies contain insoluble calcium oxalates which can cause mild mouth irritation if chewed by pets. For pet-friendly offices, Spider Plants and Boston Ferns are safer non-toxic alternatives.
Does Good Cleaner Co. wipe plant leaves during office cleaning visits?
Yes. As part of our comprehensive commercial office cleaning checklists, technicians gently dust large plant leaves with damp microfibre cloths so plants can breathe and filter air efficiently.
What is the easiest plant for a busy office?
The Snake Plant is the easiest. It tolerates low light, irregular watering, and temperature swings, and it keeps filtering air even when it is slightly neglected.
Do office plants attract pests?
Any plant can attract pests if it is overwatered or left in stagnant air. Using well-draining pots, checking leaves during monthly dusting, and isolating any new plant for a couple of weeks keeps problems rare. A quick wipe of the leaves with soapy water handles most small infestations early.
Should I water office plants on the same schedule as my cleaning visit?
Not necessarily. Cleaning and watering are separate tasks, but many offices group them so plant care is not forgotten. Your cleaning team can dust leaves, and a designated staff member can handle watering.
Can plants survive in an office with only artificial light?
Yes, many can. Snake Plants, ZZ Plants, and Pothos all tolerate fluorescent and LED lighting. Just keep them a reasonable distance from the light source and avoid placing them in completely dark corners.
Will plants survive the weekend if nobody waters them?
Most of the plants on this list were chosen partly because they tolerate being left alone. Snake Plants, ZZ Plants, and Pothos can go a week or more between waterings, which makes them forgiving choices for offices that empty out on weekends.
Can office plants help with dry winter air?
Yes, though modestly. Plants release moisture through their leaves, which adds a little humidity to dry heated offices. The effect is small compared to a humidifier, but every bit helps with static and dry skin during Ottawa winters.
How do I get a quote for office cleaning with plant care in Ottawa?
Contact Good Cleaner Co. with your office size and layout, and we will build a cleaning plan that includes leaf dusting and plant-friendly practices. We will also note which corners are hardest to reach so the cleaning team gives them the attention they need.
Wrapping Up
Office plants work best when they are chosen for the light, watering routine, and available care time, not for a sweeping claim about air quality. Place pots where they will not block walkways, emergency equipment, or cleaning access. Use trays that protect desks and flooring, remove fallen leaves promptly, and assign watering to a named person so the plants do not become an after-hours mystery. A small number of well-kept plants can make a workspace feel considered. They still need ordinary dusting, spill cleanup, and waste removal around them.
