Once you’ve changed your filter, the “Check Filter or “Check Pre-Filter” light will remain on until it’s reset. While the air purifier is powered on, press the lighted button and hold for approximately 2 seconds until the light turns off. If the HPA3300 is too expensive, I’d recommend our budget pick, the Lasko LP300. It currently costs about $87 and has affordable filter replacements. At more than 20 pounds, the Honeywell HPA3300 is heavy, especially when you try to carry it one-handed.
This is the first air purifier I’ve used, and it definitely helped this winter when it was too cold to open the windows. It’s likely that my area will have some air quality advisories this summer, and I have no doubt Honeywell’s True HEPA air purifier will freshen the air inside my apartment. Since the candle test, I’ve used it for trash odors, pizza drippings in the oven, burned toast, that oily smell from frying chicken wings and even neighbors’ cigarette smoke from the sidewalk outside my window. I expect this will come in handy on poor air quality days particularly during the summer months. The odor-reducing pre-filter should be changed every three months while the HEPA filters should be replaced every 12 months.
If this is the first time you’re using a Honeywell Portable Air Purifier, you’ll want to ensure that you have removed the protective plastic wrap from the air cleaner’s filters. The noise may also be an indicator that it’s time to replace the air purifier’s filter. Room air purifiers can often run loud when their filters contain high amounts of airborne particles. This can block the pores in a filter and stop the air from passing through efficiently.
Set on high, the AP-1512HH reduced the particulate concentration by 99.9% in the first hour. With the purifier set on medium over the next two hours, the particulate load remained stable, varying no more than 0.1%. In the first hour on high, the Airmega 400 also reduced the particulate concentration by 99.9%, and thereafter the particulate load varied by no more than 0.2% on medium.
It’s been working flawlessly in our first year of long-term testing in a New York City apartment. An activated charcoal carbon pre-filter is made to absorb any odors and catch the larger particulate such as hair and lint. These filters also protect your HEPA filter and prolongs the life of your air purifier.
To replace the HEPA filter, wrap the pre-filter around the stackable drums (number of drums varies based on model).Lastly, reinstall the filter assembly, replace the end-cap, and insert locking mechanism, turning it clockwise. Finally, discard the used filter and plug the unit back into the power source to resume receiving clean, fresh air. I was also pleasantly surprised by how quiet this best air purifier is. Even on its highest setting, it’s no louder than my tower fan or furnace. The sound is also smooth and consistent, so it blends into the background.
You can place your Honeywell HEPA air purifier in any space where you need fresh, clean air. For example, you can use it in the bathroom, kitchen, bedroom, basement, or family room. Be sure to place your air purifier in a space that falls within the air purifier’s specified coverage area for optimal performance.
The 200M has a square grille rather than a round one, but that’s the only major physical difference. If you prefer the 200M’s looks or you find it at a better price, we recommend it. The True HEPA Replacement Filter R captures 99.97 percent of airborne particles as small as 0.3 microns to help you establish a cleaner breathing experience for you and those around you. Plus, its advanced design delivers cost-efficient performance by providing up to one year of filtration before replacement is required. The Honeywell QuietCare and Enviracaire air purifiers both come with a manufacturer’s limited five-year warranty.
A higher number is indicative in revealing how efficient the air purifier performs in filtering the air. The blue ENERGY STAR symbol featured on an air purifier means that you’ll be selecting an air cleaner that is more energy efficient honeywell purifier than standard models. ENERGY STAR Air Purifiers are capable of saving you almost 27% more energy (% varies on use) when compared to standard air cleaners. This portable air purifier works with the Honeywell A and A+ Pre-Filter.
To mitigate my allergies, I’ve tested dozens of air purifiers, and only the best remain in my home to keep me from sneezing and itching my eyes raw. The best of the best is the Honeywell HPA3300BV1 PowerPlus True HEPA Air Purifier. The GermGuardian AC5900WCA was a star performer in our 2019 test, but we also found it to be much louder than the top-pick Coway Mighty, measuring 47 decibels versus 39, on its quiet/medium setting.
