AirDoctor Purifier Model Breakdown: Finding Your Perfect Fit
AirDoctor provides a selection of air purifiers, each tailored to different room sizes and purification demands. From the compact AirDoctor 1000 to the powerful AirDoctor 5500, understanding their capabilities will guide you to the best choice for your space. Here’s a detailed look at each model:
AirDoctor 1000: Compact Power for Smaller Spaces
The AirDoctor 1000 is designed for rooms up to 285 sq. ft. (with 4 air changes per hour) or 570 sq. ft. (with 2 air changes per hour). Its compact tower design doesn’t compromise on performance, boasting a CADR (Clean Air Delivery Rate) of 152 CFM (Cubic Feet per Minute) for smoke. This air doctor purifier features a four-fan speed setting and incorporates a sophisticated air quality particle sensor with an indicator light, automatically adjusting fan speed in auto mode to maintain optimal air purity.
Filtration is at the heart of the AirDoctor 1000, featuring a three-stage system: a pre-filter attached to the UltraHEPA filter, a Carbon/VOC filter, and an H13 UltraHEPA filter. This combination targets a wide range of pollutants, from large particles to volatile organic compounds (VOCs). Filter replacement is recommended every 6 months for the filter set, ensuring consistent performance. Operating at 120V/60Hz, the AirDoctor 1000 maintains a quiet operation, ranging from 34 dB at the lowest speed to 54 dB at the highest. Its dimensions are 9” (W) x 9” (D) x 23” (H), and it weighs just 10 lbs, making it easily portable.
AirDoctor 2000 and 2000i: Enhanced Filtration for Medium Rooms
Stepping up in size, the AirDoctor 2000 and 2000i models are suitable for rooms up to 305 sq. ft. (4x air changes/hour) or 610 sq. ft. (2x air changes/hour). These models offer a CADR of 162 CFM for smoke and maintain the four-fan speed system, air quality sensor, and indicator light found in the 1000. The “i” version indicates Wi-Fi connectivity for smart control.
The filtration system in the 2000 series includes a pre-filter attached to the Carbon/VOC filter, a separate Carbon/VOC filter, and an H13 UltraHEPA filter. This configuration effectively captures particles and gases. Filter replacement intervals are every 6 months for the Carbon/VOC filter and every 12 months for the UltraHEPA filter. Operating at 120V/60Hz, the sound levels are slightly higher than the 1000, ranging from 40 dB to 55 dB. The dimensions are 13.85″ (W) x 6.6″ (D) x 18.72″ (H), and it weighs 10 lbs, featuring built-in, recessed handles for easier movement.
AirDoctor 2500: Balancing Power and Coverage
The AirDoctor 2500 is designed for larger rooms, covering up to 420 sq. ft. at 4 air changes per hour and 840 sq. ft. at 2 air changes per hour. With a CADR of 220 CFM for smoke, it provides a significant boost in air cleaning capacity. It retains the four-fan speed settings, air quality sensor, and indicator light for automated operation.
Like the 2000 series, the AirDoctor 2500 uses a pre-filter attached to the Carbon/VOC filter, a separate Carbon/VOC filter, and an H13 UltraHEPA filter. Filter replacement schedules are the same: Carbon/VOC every 6 months and UltraHEPA every 12 months. Operating at 120V/60Hz, the noise levels are similar to the 2000 series, from 34 dB to 59 dB. Dimensions are 15.9” (W) x 7.7” (D) x 20.7” (H), and it weighs 16.3 lbs, also equipped with built-in, recessed handles.
AirDoctor 3500 and 3500i: Powerful Purification for Larger Living Spaces
The AirDoctor 3500 and 3500i are designed for substantial rooms, offering coverage up to 630 sq. ft. at 4 air changes per hour and 1,260 sq. ft. at 2 air changes per hour. The CADR for smoke is significantly higher at 340 CFM, reflecting its enhanced purification capability. The “i” model includes Wi-Fi connectivity. These models maintain the four-fan speeds, air quality sensor, and auto mode.
Filtration remains consistent with the 2500, utilizing a pre-filter attached to the Carbon/VOC filter, a separate Carbon/VOC filter, and an H13 UltraHEPA filter, with the same filter replacement recommendations. Operating at 120V/60Hz, the sound levels range from 39 dB to 59 dB. The dimensions are 15.75″ (W) x 8.75″ (D) x 23″ (H), and it weighs 18 lbs, featuring built-in, recessed handles for portability.
AirDoctor 5500 and 5500i: Maximum Coverage for Large Rooms and Open Areas
For the largest spaces, the AirDoctor 5500 and 5500i offer the most extensive coverage, handling up to 1,043 sq. ft. at 4 air changes per hour and 2,086 sq. ft. at 2 air changes per hour. The CADR for smoke is an impressive 556 CFM, making it the most powerful air doctor purifier in the lineup. It features six fan speeds, providing more granular control over airflow, and includes the standard air quality sensor and auto mode.
The 5500 series boasts a doubled-up filtration system with two permanent pre-filters, two Carbon/VOC filters, and two H13 UltraHEPA filters, maximizing particle and gas removal. Filter replacement is recommended every 6 months for the Carbon/VOC filters and every 12 months for the UltraHEPA filters. Operating at 120V/60Hz, it is surprisingly quiet for its size and power, with sound levels from 30 dB to 50 dB. The dimensions are 16” (D) x 16” (D) x 28.75” (H), and it weighs 33 lbs, equipped with built-in, hidden casters and recessed handles for easier maneuverability despite its larger size.
Understanding Key Air Purifier Features: CADR, Room Coverage, and Filtration
When choosing an air doctor purifier, several key features should be considered to ensure you select the right model for your needs:
-
CADR (Clean Air Delivery Rate): This is a crucial metric for comparing air purifier performance. CADR measures how quickly an air purifier cleans a room of smoke, dust, and pollen. A higher CADR value indicates faster and more effective air purification. The CDC recommends a CADR that is at least 2/3 of the room’s square footage.
-
Room Size Coverage: Air purifiers are designed for specific room sizes. Coverage is often specified with two values, representing 4 air changes per hour (ACH) and 2 ACH. For effective virus and bacteria removal, experts like Harvard University (cited by the CDC) recommend at least 4 ACH.
-
Filtration System: AirDoctor purifiers utilize a multi-stage filtration system, typically including:
- Pre-Filter: Captures larger particles like dust and pet hair, extending the life of other filters.
- Carbon/VOC Filter: Removes odors, gases, and volatile organic compounds (VOCs) from household products and pollutants.
- H13 UltraHEPA Filter: Captures 99.97% of particles as small as 0.3 microns, including dust, pollen, mold spores, bacteria, and viruses. H13 is a high grade of HEPA filtration, ensuring superior particle removal.
-
Air Quality Sensor and Auto Mode: These features allow the air doctor purifier to automatically monitor air quality and adjust fan speeds to maintain a desired level of cleanliness, optimizing performance and energy use.
-
Noise Levels: Consider the noise level, especially for bedrooms or living areas. AirDoctor models are designed to operate quietly, but noise levels increase at higher fan speeds.
Choosing the Right AirDoctor Purifier for Your Home
Selecting the ideal air doctor purifier depends primarily on the size of the room you need to purify.
- For small rooms (up to 300 sq. ft.), the AirDoctor 1000 or 2000/2000i are excellent choices, offering powerful filtration in a compact size.
- For medium to large rooms (300-600 sq. ft.), the AirDoctor 2500 or 3500/3500i provide enhanced coverage and CADR for more effective purification.
- For large rooms and open living spaces (over 600 sq. ft.), the AirDoctor 5500/5500i is the top choice, providing maximum coverage and the highest CADR for comprehensive air cleaning.
Consider Wi-Fi connectivity (“i” models) if you desire smart control and remote monitoring of your air doctor purifier. Regardless of the model you choose, AirDoctor purifiers are designed to provide cleaner, healthier air for your home, helping you breathe easier and live better.
*Harvard University Study cited by CDC recommends at least 4 air changes per hour to effectively remove viruses, bacteria, smoke, dust & pollen.
**CADR (Clean Air Delivery Rate) is an objective measurement for comparing air filter performance, based on its ability to remove particulate matter. The higher the number, the more effective it will be. According to CDC guidance, CADR/cfm should be 2/3 of the total room size.
