AirPura T700 Air Purifier

The T700 is purpose-built for heavy smoke. Unlike standard air purifiers, it uses a massive 26-pound activated carbon filter specifically designed to adsorb the chemicals and tars found in tobacco and marijuana smoke, rather than just filtering out dust.

The TarBarrier pre-filter should be vacuumed regularly and replaced every few months depending on smoke levels. The main 26-pound carbon filter typically lasts 18 to 24 months, while the HEPA barrier filter is designed to last 3 to 5 years under normal residential use.

You can absolutely use it in a smaller room, but it is designed for large spaces up to 2,000 square feet. If you place it in a smaller area, you can simply run it on a lower fan speed, which will actually increase the dwell time—the amount of time air spends in contact with the carbon—making it even more effective at removing odors.

The T700 is relatively quiet for its size, but it is not silent. At lower speeds, it produces a gentle white noise that is generally unobtrusive, though you will notice a more significant airflow sound if you run it at the highest setting.

It is highly effective at capturing smoke-related particles, but it is not a medical-grade HEPA purifier. It captures 95% of particles down to 1 micron, which is excellent for smoke, dust, and pollen, but it may not catch the ultra-fine allergens that a True HEPA filter (99.97% at 0.3 microns) would.

Yes, the unit comes equipped with integrated casters, making it easy to roll across hard floors or low-pile carpets. Despite its robust steel construction and heavy carbon filter, the wheels allow you to reposition it without needing to lift the unit.
