Works Beautifully
We purchased one of these on sale in the hope it would help moderate the severity of pollen season in upstate NY and the dander generated by two large labradors. It has a nice, clean look and small foot print, which we feel is important.The HEPA filter was shipped inside it in a bag that needs to be removed but doing so was incredibly quick and easy to do. Twist the top a quarter turn and place to one side. Lift out the filter, remove the bag, lower the filter back in using the two tabs provided on it for that purpose, lift the lid back on and quarter twist to close. It takes 2 mins. Then its’ plug-in, turn on and choose “”Auto” or a fan speed using the touch sensitive panel on top. You can control it from your iphone if you’re into that but it certainly isn’t necessary.The first thing we noticed is how quiet it is. Effectively soundless in sleep mode and at fan speed 1. Barely noticeable at fan speed 2, unless you’re right next to it, noticeable at fan speed 3 when you are in the same room as it but not obnoxious. Noticeably louder at fan speed 4 which should be considered a ‘Turbo” mode. Then we noticed the impact of running it – vastly reduced swelling of the eyes and sinuses of those suffering from hay fever and a significant reduction in the doggy smell of our labradors. It works really well.We have taken advantage of the ability to control this by iPhone to set a schedule where it automatically runs in sleep mode (low, continuous fan) from 10pm to 5am. Then at fan speed 2 from 5am to 5:30am, ramping up to fan speed 3 from 5:30am to 8am before switching to auto from 8am to 10pm. Because of the relatively severe allergies suffered by a couple of our family members the P2.5 micron threshold is set to 2 ug per meter cubed and this filter has been able to attain that incredibly low level with that schedule within a few hours of all windows and doors to the outside being closed to the 1800 sq. ft area it services. At this point we have an oasis for our hay fever sufferers to return to each evening and it’s made an incredible difference to their comfort. Do they still take Claritin or Allegra during pollen season? Yes, we’ve found it necessary to deal with the pollen at work and in the garden. Are they doing better than they were before we got this filter? Yes, the continuously swollen and itchy, weeping eyes are gone. The inflamed nasal passages are gone. Their sleep deprivation is gone. Their quality of life has improved dramatically. We had no idea how dramatic an impact adding a quality, appropriately sized HEPA filtration system would have. This unit is rated for something like 3000 sq. ft. We’re using to control air quality in a 1800 sq.f.t open plan area and its doing a great job of that without having to run the fan at high speed for prolonged periods of time.We’ve had this for several weeks now and experienced 1st hand how well it can deal with really terrible air quality when the smoke from the fires in Quebec blew into NY. Opening the door to come into the house with the shopping during the worst of it briefly dropped the air quality from a PM2.5 of 001 to as high as a PM2.5 of 185 within 12 feet of the door. This was then quickly reduced to a PM2.5 of less than 20 in an hour and back to 001 in about 2 hours after the door was closed. The outside airs PM2.5 was apparently North of 300 at this time (sources accuweather and the news), the air was literally a hazy brown like smog and this filter was able to detect it, automatically adjust its fan speed to clear it and maintain perfect air quality in the house.Does it work? Absolutely, quietly and brilliantly.Would we buy this again? Yes, in fact we have so that we can control the air quality for one of our allergy sufferers in another area where they have to spend prolonged periods of time. That one’s been in place for about 3 weeks and has done exactly what we hoped it would do – improve the quality of life at work in a 7000 sq.ft. open plan office area. Now this is well beyond the manufacturers claimed coverage for a unit and it looks like they’re right based on who’s apparently benefiting and who isn’t but here’s the important point. The benefits to the workforce have been so noticeable to management they’re now considering upgrading the offices HVAC system to include HEPA filtration. I think that speaks volumes.

Cleans the air quickly
Levoit Core 600S Review (5/5 Stars)Excellent for large rooms (up to 635 sq ft, 5x/hour). Powerful CADR (410 CFM) quickly clears dust, allergens, smoke, odors. Smart app, Alexa control, accurate laser sensor, auto mode, quiet sleep mode (26dB).Noticeably reduced allergies and dust buildup. Great value vs. performance.Pros: Effective filtration, smart features, low noise.Cons: Filter replacements ~$80/6-12 months, no washable pre-filter.Highly recommend for open spaces.

Very pleased with my 400 air purifier. The first day of using it our house had lost its locked up winter smell. Watching it automatically increase in speed catching the cooking smells is incredible and it really works.Using it now for a couple of weeks its noticeably helped us with our dust & Spring allergies 👍Answering some of the negative reviews. Yes the bottom come will come off easily if it hasn’t been LOCKED in place properly and I can hear an electrical hum on auto/ sleep modes at NIGHT, so I leave it on low speed when sleeping.I recommend it and am now looking at buying a smaller one just for our bathroom.

Après plusieurs années d’utilisation et de recommandations, je fais un retour sur ce purificateur d’air.Celui-ci continue encore aujourd’hui de me donner entière satisfaction.Voici plusieurs points positifs que j’ai relevés :_ De nombreuses fonctionnalités intéressantes et utiles comme la possibilité d’éteindre l’éclairage ou le mode nuit (je confirme qu’il est possible de dormir avec le purificateur d’air en fonctionnement dans la chambre)._ Le capteur de particules fines est un vrai plus ! (dommage qu’il ne soit pas sur tous les modèles de la marque)_ L’application Vesync est simple à utiliser et assez complète. Elle donne accès à plusieurs informations utiles telles que la durée de vie du filtre, la programmation de l’allumage ou de l’extinction, ainsi qu’un graphique de l’historique de la qualité de l’air. Elle permet de surveiller la qualité d’air même lorsque vous n’êtes pas chez vous…Je l’ai testé dans de nombreuses conditions, et il s’est toujours montré très efficace, même dans des pièces avec un grand volume.J’ai également apprécié sa compatibilité avec Home assistant, qui m’a permis d’accéder à des fonctionnalités supplémentaires comme l’envoi de notifications pour m’alerter de la dégradation de la qualité de l’air ou l’activation automatique de l’appareil si elle dépasse une certaine valeur.Les côtés moins appréciables :_ Le filtre est très onéreux (il peut durée plusieurs années ou seulement quelques mois selon la qualité de l’air ambiant). Attention à ne pas l’utiliser pendant que vous cuisinez car cela impactera rapidement la durée de vie du filtre.En résumé je ne regrette pas mon achat (bien au contraire, j’ai même investi dans un autre modèle plus petit) . Lorsqu’il est en marche dans une pièce, on sent réellement une différence, notamment une réduction des odeurs, même dans un environnement déjà sain.
