these very fine particles and pollutants reaches up to 95%. It follows, then, that since there are less of these particles in the air, you may expect a reduction in the necessity for dusting and cleaning and a longer time interval between redecorating.

Particle sizes of pollutants vary and are measured in microns. A micron is 1/25,400th of an inch. A commonly used illustration of their size is that it would take 200 microns to reach across a dot made by a sharp pencil. The accompanying chart shows the range of sizes, in microns, of the most common pollutants.

OPERATION

Household dust is typically an accumulation of particles in a size range of .01 micron (1/2,540,000th of an inch — invisible to the naked eye) up to 100 microns (the diameter of a human hair). Pollens and spores, which can aggravate allergy symptoms, are usually in the 10-100 micron size range.

The efficiency of the Aprilaire® Air Cleaner Media on the smallest particle which can be seen with the naked eye (approximately 10 microns) reaches 99%.

2250 & 2400 specifications

Aprilaire has long been a leader in indoor air quality solutions, and the Aprilaire 2250 and 2400 models are prime examples of their dedication to innovation and efficiency in whole-house humidification. Each of these models is designed to provide optimal humidity levels, enhancing comfort and protecting your home from the detrimental effects of dry air.

The Aprilaire 2250 is an advanced whole-house evaporative humidifier that offers a capacity of up to 12 gallons of moisture per day. It is ideal for homes up to 4,200 square feet, making it suitable for medium to large residences. One of its standout features is the built-in adjustable humidistat, which allows homeowners to set precise humidity levels according to their preferences. This ensures that the indoor environment remains comfortable throughout the year.

The Aprilaire 2400, on the other hand, is designed for larger homes, capable of handling up to 17 gallons of moisture per day. It is suited for homes up to 6,200 square feet and incorporates advanced features for efficient performance. A significant characteristic of the 2400 model is its self-regulating capabilities, which enable it to adapt to the varying conditions in your home, maintaining consistent humidity levels regardless of changes outside.

Both models utilize evaporative technology, which draws in household air and passes it through a moistened filter. As the air flows through, it absorbs moisture, effectively raising the humidity level before circulating back into the home. This method is energy-efficient and prevents the over-saturation of humidity that can occur with other types of humidifiers.

Additionally, the Aprilaire 2250 and 2400 are equipped with easy-to-clean components, ensuring that maintenance is straightforward. Their durable construction promises longevity, making them a wise investment for homeowners concerned about air quality.

In summary, the Aprilaire 2250 and 2400 models offer advanced features and technologies tailored for comprehensive humidification. With adjustable settings, self-regulating functions, and energy-efficient evaporative technology, both humidifiers stand out in the market. Homeowners can enjoy enhanced comfort while protecting their living spaces, ultimately leading to a healthier indoor environment through optimal humidity control.
