Air Purifiers for Home Large Room, Covers up to 1588 Sq. Ft, Smart WiFi and PM2.5 Monitor, H13 True HEPA Filter Removes 99.97% of Particles, Pet Allergies, Smoke, Dust, Auto Mode, Alexa Control

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.

Funciona como esperado. Se ve de calidad. Es grande. En velocidad 1 no es ruidoso, en 2 es aceptable y 3 o 4 ya no valdrían para dormir.

Den är jätte bra den funkar.

منقي هواء ممتاز وانصح به لو انت تعيش في بيئة تحتاج منقي

Premetto che abiti in un appartamento di 50 mq con vani, ma senza porte. Non è un totale open space: semplicemente abbiamo eliminato tutte le porte. Comprato il purificatore principalmente per le ore notturne causa impossibilità di tenere le finestre aperte, poiché abitando a pian terreno con finestre camera da letto verso strada, di notte il passaggio umano senza rispetto altrui è di routine. Il dispositivo è stato collegato ad Alexa (in meno di 2 minuti) in routine. Routine 7gg/7gg per 8 ore. In modalità notturna non si percepisce e fa il suo dovere con soddisfazione. PMI 2.5 allo start a 7, alla mattina 1. Oggi è capitato di bruciare un toast. Un casino totale. L’appartamento pieno di fumo e odore di bruciato. Acceso il purificatore via app in modalità filtrazione al massimo (velocità 4) e (per onestà) finestre aperte. Start: 969 x PMI 2.5 A 743 x PMI 2,5 odore di bruciato impercettibile Dopo 10 minuti dall’avvio del purificatore PMI 2.5 risultava a 293 Dopo 12 minuti dall’avvio del purificatore PMI 2.5 risultava a 380 (aumentato) Dopo 30 minuti dall’avvio del purificatore PMI 2.5 risultava a 38 Dopo 40 minuti dall’avvio del purificatore PMI 2.5 risultava a 16 Contro: il sensore di “inquinamento” è lento nella rilevazione e non subito affidabile, ma sicuramente è dovuto al fatto che sia all’interno del device. Ci vogliono svariati minuti prima che vi arrivi l’alert via app. Pro: in modalità notturna non si sente e lavora per voi. Il sensore “luci” è fantastico: spegnete le luci oppure le dimmerate in soffuse e il display si spegne. Compatibilità con skill Alexa meravigliosa e velocissima. Gli odori li elimina velocemente. In fase di valutazione: il filtro (che costa a oggi sui 56€) dovrebbe essere performante per circa 1 anno. Non è specificato per quanto filtraggio e utilizzo giornaliero. Ve lo sapremo dire. Quindi recensione in aggiornamento. Conclusioni: non farei affidamento ai mq, ma alla propria routine di vita. Il purificatore che abbiamo comprato è per un appartamento fino a 147 mq (il triplo del nostro) per un semplice motivo: prima filtri, meno spendi in energia ovvero: meno ti costa il purificatore secondo la metratura dell’appartamento, più spendi in energia per purificare. Infine: meno filtri, più ti dura il filtro che ha un costo. Valuteremo se i parametri scelti siano corretti. Al momento, dopo un mese quotidiano di utilizzo, possiamo semplicemente consigliarlo visto il rapporto qualità/prezzo rispetto ad altri brand conosciuti e apprezzati, ma con discontinuità di reperimento ricambi (filtri)
