Plants for the Bedroom: Better Sleep through Natural Air Purification

Restless sleep, morning tiredness despite enough hours in bed, waking up at night without an obvious reason – many people suffer from poor sleep quality. The cause often lies in the air quality of the bedroom. The right plants can naturally solve these problems and provide restful, deep sleep.

At a glance:

  • Snake plant produces oxygen at night instead of CO₂
  • 2-3 plants are enough for a 12-15m² bedroom
  • NASA-confirmed pollutant filtering during sleep
  • Also suitable for dark & cool bedrooms

1. Why air quality in the bedroom affects sleep


While we sleep, we spend 6-8 hours in an enclosed room...
Measurable consequences of poor air quality:
  • Increased CO2 levels cause headaches
  • Dry air irritates the airways

Poor indoor air quality shortens deep sleep phases.

2. Plants in the Bedroom – Myth or Science?


For a long time, the myth persisted that plants are harmful at night because they consume oxygen and release carbon dioxide. However, this concern is unfounded. The amount of carbon dioxide that plants produce at night is negligible compared to the amount exhaled by a sleeping person.
Scientifically proven benefits of plants in the bedroom:
  • Continuous air purification from pollutants
  • Increase of air moisture (ideal for dry heated air)
  • Reduction of dust particles in the air
  • Psychological effect: Green has a calming and stress-reducing effect
  • Improvement of oxygen supply (in CAM plants)

3. The best plants for the bedroom


The key is choosing the right plants. Certain kinds are especially suited for the bedroom and have been proven to improve sleep quality. The NASA Clean Air Study identified several highly effective plants – three of which are available in the AIRY System.

4. Plants for special situations


Cool bedrooms (16-18°C)

Many people sleep better at cooler temperatures. These plants also tolerate 16-18°C or below:

✅ Available in the AIRY system:

  • Snake plant: Up to 10°C – extremely cold-hardy
  • Spider plant: Up to 12°C – no problems in the cool bedroom

Other cold-tolerant plants:

  • Aloe vera, pothos, peace lily

To avoid: tropical plants like flamingo flower or orchid, which need warmth.

Bedroom with little light

North side, small windows, dark corners? These plants also thrive with 2-3 hours of daylight:

✅ Available in the AIRY system:

  • Snake plant: Extreme shade tolerance
  • Spider plant: Grows well in partial shade

Other shade-tolerant plants:

  • Peace lily (thrives even in very dark corners)
  • Devil's ivy, Zanzibar gem

How many plants per bedroom?

Room size Recommendation Example combination
Up to 12 m² 2-3 plants 1 Bow snake plant + 1 Golden fruit palm
12-20 m² 3-5 plants 2 bow snake plants + 1 spider plant + 1 peace lily
Over 20 m² 5-7 plants 2 Bow Sansevieria + 2 Spider Plants + 1 Areca Palm

💡 Placement for maximum effect:

Large plants in corners (snake plant, golden cane palm in the AIRY system)
• Hanging plants on cupboards (spider plant, devil's ivy)
• Small plants on bedside tables (aloe vera)
• Spread throughout the room for even air purification

5. Increase humidity in the bedroom


Dry air in the bedroom (below 40% humidity) leads to irritated mucous membranes, dry throat, and increased susceptibility to colds. Especially during the heating season, the humidity often drops to 20-30% – well below the healthy range of 40-60%.
Top plants for air humidification:

✅ Available in the AIRY System:

  • Gold fruit palm: Highest humidifying performance (up to 2L water/day) – top choice for dry rooms
  • Spider plant: 200-300ml/day evaporation – very effective with moderate space needs
  • Snake plant: Moderate humidifying + nighttime oxygen production – ideal combination

Other air-humidifying plants:

  • Peace lily (+5% air moisture)
  • Devil’s ivy (continuous moisture release)
  • Dry air irritates the airways

💡 Optimal combination for a 15m² bedroom:

1 golden fruit palm + 2 spider plants = 40-60% air moisture Or:

2-3 spider plants + 1-2 bow snake plants for a more compact solution

Tip: Combine several plants for the best effect. The more plants, the stronger the moistening – naturally without electricity costs or technical devices.

6. AIRY system for optimal air purification


While plants in regular pots already exert their effect, the AIRY system enhances air purification through active root ventilation. The NASA Clean Air Study found that 90% of the air cleaning takes place in the root zone – exactly where the AIRY system works.

The NASA finding:

90% of pollutant filtering is done by microorganisms in the root zone, not by the leaves. The AIRY system activates precisely this area through continuous air circulation.

Standard pot: Root zone largely enclosed

AIRY system: Active air guidance through the entire root zone

Benefits in the bedroom:

  • Maximum air purification through optimized root ventilation
  • Significantly more effective than standard pots
  • Even water supply (water tank for 1-3 weeks)
  • No waterlogging due to optimal ventilation
  • Silent – no disturbing humming like with air purifiers
  • No electricity use, no upkeep
  • Natural solution instead of technical devices

NASA-funded: Especially snake plant, peace lily, and spider plant use their full air-purifying potential in the AIRY system and ensure measurably better air quality during sleep.

7. Practical Tips for Plants in the Bedroom


Placement & Location

  • Not directly next to the pillow (distance of 50-100 cm ideal)
  • Elevated position prevents accidental knocking over at night
  • No plants on shaky bedside tables
  • Distribute plants around the room for even air cleansing

Care routine

  • Water in the morning, not in the evening (prevents too much moisture at night)
  • Wipe leaves monthly (better air cleansing)
  • Check regularly for pests
  • Fertilize only during the growing season (March-September)

Cleanliness

  • Check the soil for mold (occurs with overwatering)
  • Use high-quality growing medium
  • Ensure good drainage
  • Air out the bedroom in the morning

8. Common Questions About Plants in the Bedroom


Are plants in the bedroom dangerous at night?

No, that is a myth. The amount of CO₂ that plants produce at night is negligible compared to the CO₂ exhaled by a sleeping person. The positive effects (air purification, increased air moisture, psychological impact) far outweigh it.

Which plants produce oxygen at night?

Only CAM plants produce oxygen at night instead of CO₂:

Snake Plant (Sansevieria) – absolute top choice for the bedroom, available in the AIRY system
• Aloe Vera – also a CAM plant, but requires more light

All other plants (Spider Plant, Peace Lily, Devil’s Ivy) release CO₂ at night – in harmlessly small amounts.

Which plants are best for the bedroom?

The best combination for most bedrooms: Snake Plant (produces oxygen at night, NASA top plant), Spider Plant (NASA top 3 air purifier, very easy to care for), and Areca Palm (highest air humidification, non-toxic for children & pets). All three are available in the AIRY system for maximum air purification.

Other recommended plants: Peace Lily (highest filtering power + humidity), Aloe Vera (CAM plant), Devil’s Ivy (formaldehyde specialist).

How many plants do I need for better sleep?

For a bedroom of 12-15m², 2-3 medium-sized plants are sufficient. Recommendation: 1-2 snake plants + 1 spider plant as a base. For larger rooms (over 20m²), 5-7 plants are optimal. More important than the number is the choice of the right types – snake plants and spider plants are scientifically the best tested.

Which plants are poisonous to pets?

Non-toxic (safe with pets):Gold fruit palm – completely non-toxic for cats, dogs, and children
Only slightly toxic (mostly harmless):Snake plant, spider plant
Toxic (keep out of reach):Peace lily, devil’s ivy, aloe vera

Tip for households with pets:Gold fruit palm is the best choice – non-toxic, NASA-tested, highest air humidification. Available in the AIRY system.

Where is the best place to put plants in the bedroom?

Ideally, a distance of 50-100 cm from the pillow. Recommended placement: Large plants (snake plant, golden cane palm in the AIRY system) in corners, hanging plants (spider plant, pothos) on cabinets or shelves, small plants (aloe vera) on bedside tables. Distribute several plants throughout the room for even air purification – do not concentrate them all in one place.
