Shark HC502 3-in-1 MAX Features and Specifications

Shark HC502 3-in-1 MAX air purifier is a large unit with physical dimensions of (L x W x D) 12.59 x 12.59 x 29.52 inches (~32 x 32 x 75 cm), and it weighs 17.63 pounds (~8 kg).

The unit is very stable, but don't let the pets and kids play around it - if pushed with strong enough force, it may tumble over.

Air intakes are at the lower part of the unit, where the air filter is positioned, while the air exhaust is at the top of the unit.

In order to purify air at the required level, it is recommended to place the unit at least 3 feet (0.9 meters) away from other objects.

Also, the Shark HC502 3-in-1 MAX air purifier features a tilt/rotating mechanism, allowing the unit to cover a larger area.

Shark HC502 3-in-1 MAX air purifier is designed as three units in one:

• true HEPA air purifier,
• true HEPA air purifier + air heater,
• true HEPA air purifier + fan.

As an air true HEPA air purifier and air heater, Shark HC502 3-in-1 MAX Air Purifier is rated at 1500W (120V 12.5A AC).

As stated by the manufacturer, the unit is intended for rooms up to 1000 square feet (92.9 m²) based on one air purification cycle per hour.

Personally, when recommending air purifiers, one should aim at more air purification cycles per hour - if we assume 3 cycles per hour, that means that Shark HC502 3-in-1 MAX Air Purifier is suitable for rooms and areas up to 333 square feet (~31 m²), which is still a sizeable room/area.

Shark HC502 3-in-1 MAX Air Purifier features a detachable remote control positioned on top of the unit - controls may be left on the unit or can be used detached from the unit.

Controls are simple and easy to use. They include:

• PowerOn/Off button,
• Heating Controls,
• Timer,
• Fan Controls,
• Brightness control button,
• Auto Mode button,
• Air Info button,
• Oscillation control button.

Additional controls include:

• Turn Off Sound: press and hold the Brightness button for 3 seconds,
• Turn On/Off Child Safety Lock: press and hold the Timer and Oscillation buttons,
• Temperature Display: press and hold Fan and Thermometer buttons to change the thermometer display from Fahrenheit to Celsius degrees,
• Reset Filter Life: press and hold the Air Info button for 3 seconds.

Shark HC502 3-in-1 MAX Air Purifier features an air sensor that measures air quality and provides a direct reading on the digital display on the front of the unit using three colors and numbers:

• Good Air Quality: Blue color, 85-100%, number of measured air particles 0-25,
• Fair Air Quality: Orange color, 70-84%, number of measured air particles 26-80,
• Poor Air Quality: Red color, 0-69%, number of measured air particles 81+.

Personally, when used exclusively as an air purifier, Shark HC502 3-in-1 MAX Air Purifier should be set in Auto Mode, letting the unit measure air quality and automatically adjust the fan speed.

Air filtration is based on the use of a high-quality HEPA air filter, which uses several three different layers for more thorough air purification:

• Air Pre-Filter captures larger airborne particles, including larger particles of dust, pet dander, and similar, protecting inner air filters,
• Carbon Air Filter captures fumes, odors, Volatile Organic Compounds (VOCs), smoke, and similar.
• True HEPA air filter captures very fine particles.

Thanks to such air filter construction, Shark HC502 3-in-1 MAX Air Purifier is able to capture 99.98% of 0.1-0.2 microns or larger particles, which is an excellent result.

Note: when the unit arrives, its air filter is delivered in a plastic protective cover, which must be removed before the very first use. Although the Shark HC502 3-in-1 MAX Air Purifier is very simple and intuitive to use, when the unit arrives, be sure to read the manual thoroughly in order to get accustomed to your new air purifier.

Air filter must be replaced every 6-12 months, depending on the unit's use and the type and amount of air pollutants.

Shark offers two types of air filters for the Shark HC502 air purifier:

• Shark Air Purifier MAX Anti-Allergen Filter with True HEPA,
• Shark Air Purifier MAX Anti-Allergen Filter with True HEPA + Microban

Microban reduces bacteria growth on the HEPA air filter, but it also increases the price of the air filter.

Personally, since the quality of air purification greatly depends on the air filter, don't go cheap - go for the OEM air filter with Microban. After all, the price difference is more than acceptable.

Shark HC502 3-in-1 MAX Air Purifier comes with a 2-year limited warranty.

Long Story Short: If You are looking for a relatively simple to set, use and maintain air purifier, consider Shark HC502 3-in-1 MAX Air Purifier, Heater & Fan.

As its name suggests, it is designed as a 3-in-1 unit and can be used as an air purifier only, air purifier + heater, and air purifier + fan.

The unit features excellent air filtration and remote control, but it doesn't support Amazon Alexa, and Google Home Assistant - many users actually prefer it because of that.
