Customer Reviews
Real reviews from verified customers across Kenya
“I bought this for my daughter's bedroom after we discovered mold in our apartment. The difference in air quality was noticeable within two days! The PM2.5 display dropped from the red zone to green. Totally worth it — MoldGuard Kenya delivered the same day.”
“I was sceptical about the price but after using this for one month my wife's asthma has improved significantly. The night mode is very quiet — you barely hear it. The air quality sensor is incredibly accurate. Highly recommend for anyone dealing with dampness in Nairobi.”
“Great product for the coastal humidity. I placed it in my living room and within a week the musty smell from the walls was completely gone. The touch controls are very intuitive. MoldGuard Kenya's team helped me set it up over WhatsApp.”
“We have three children and were very concerned about the air quality in our home after a mold problem in the bathroom spread. This purifier has been running non-stop in the kids' playroom for two months and all three children have had fewer respiratory issues. Excellent machine.”
“The PM2.5 colour display alone is worth the price — you can actually see when the air is clean or dirty. I keep it in my bedroom and the auto mode handles everything. When I cook and fumes drift in, the fan speeds up automatically. Very intelligent device.”
“Good product. I bought it after seeing mold on my bedroom ceiling. Combined with the professional treatment from MoldGuard Kenya, the air now smells completely fresh. Filter replacement seems straightforward, though I haven't done it yet after 3 months.”
“I run a small home daycare and the air quality has always been a concern for me, especially with the rainy season making everything damp. This purifier runs quietly all day and the children have not had a single respiratory complaint since I got it. Worth every shilling.”
“In Mombasa the humidity and mold spores are very high. Since getting this purifier my family's health has markedly improved — especially my elderly mother who has breathing issues. The H13 filter is very effective against the coastal mold we deal with every year.”
“Cannot recommend this highly enough. I bought it when MoldGuard Kenya was treating our apartment for black mold. The technician actually recommended this specific model. After the remediation and with this running, our apartment feels like a completely different place.”
“Great purifier. The automatic mode is very handy — it adjusts by itself so I don't have to remember to change settings. My only minor concern was I expected the delivery within 24 hours but it came the next day. Still, 4 stars for the product itself.”
“MoldGuard Kenya shipped to Kisumu and the purifier arrived in good condition within 2 days. Set it up in my bedroom which always had a stale humid smell. Within 3 days the smell was gone and the PM2.5 reading stabilised in the green zone. Very satisfied.”
“I manage several rental units and bought this for a flat that had a persistent mold problem. The tenants have been very happy since I installed it combined with MoldGuard's treatment service. Will be buying for the other units as well.”
“Very good air purifier. My husband has dust allergies and since getting this his morning sneezing fits have reduced dramatically. The filter indicator makes maintenance very easy. Price was a bit high but the quality justifies it.”
“Brilliant product. I live on the ground floor and every rainy season was a nightmare for damp and mold smell. MoldGuard Kenya came and treated the mold and I got this purifier running after. The combination has completely transformed our home. Five stars.”
“I bought this as a gift for my parents who have had severe mold problems in their home for years. They say the air feels noticeably cleaner and fresher. My father, who has asthma, has had zero attacks since the purifier was installed two months ago. Excellent purchase.”
“Professional grade performance in a compact, elegant design. The night mode is genuinely silent — I sleep with it on and it doesn't disturb me at all. The colour display is a really thoughtful feature. You always know the state of your air at a glance.”
“I was worried about the long-term operating costs but at only 24W it uses about the same power as a low-energy bulb. Having it run 24/7 costs very little but the benefit to our family's health is enormous. The filter only needs changing once a year. Worth it completely.”
“I was hesitant because of the price but I'm so glad I spent it. The air in my living room used to smell stale and musty every morning. Now it's genuinely fresh when I wake up. The automatic mode means I don't have to think about it — the purifier handles everything by itself.”
“Living right by the sea the humidity and mold levels are very challenging. This purifier running overnight has made my bedroom feel completely different — lighter, cleaner air. My children sleep much better and no one wakes up with a blocked nose anymore. Excellent product.”
“My doctor recommended improving indoor air quality for my daughter who has frequent upper respiratory infections. This device combined with MoldGuard Kenya's inspection and treatment of our walls has led to a remarkable improvement in her health. I cannot put a price on that.”
“A good product that does exactly what it promises. Had it running in my bedroom for 6 weeks now and the improvement in air freshness is undeniable. The digital display showing PM2.5 levels is genuinely useful — now I understand what affects indoor air quality and when.”
“Bought this on the recommendation of my sister who had purchased one in Nairobi. MoldGuard Kenya arranged delivery to Eldoret which was faster than expected. The purifier is extremely quiet and the PM2.5 sensor is accurate. The air in my house has improved dramatically.”
“Running this in my home office and the improvement in how I feel during the day is noticeable. I used to get afternoon headaches which I never connected to poor air quality before. Since getting the purifier those headaches are almost completely gone. Very impressed.”
“The purifier works well for a smaller room. I put it in my 25 m² studio and it manages the air adequately though I feel a bigger model might work even better for the space. That said the PM2.5 reading does stay consistently in the green zone so I can't complain too much.”
“Solid product. I bought it for my bedroom after seeing black mold in the corner near the window. The same week I had MoldGuard Kenya come and treat the mold professionally. With both measures in place the problem is completely gone and the room smells perfectly clean.”
“The night mode works very well — it dims the display and runs so quietly I sometimes check if it's still on. Impressive build quality for the price. The child lock is useful since my 3-year-old kept pressing buttons on my previous purifier. This design has solved that.”
“MoldGuard Kenya delivered to Iten in under 3 days which I did not expect. The purifier has been running in my bedroom since and the air quality is noticeably better. I live at altitude where mornings can be very cold and damp and this device handles it brilliantly.”
