I no longer sneeze all the time, I love the filter! This product is wonderful.

It's significantly reduced my allergies and asthma complications within my apartment. Reviewer: Terry Dunn Sr So far I like the cleaner very much. Just been using it for a couple of weeks I bought this for my office. It is a little too big for my office. So I kept at the low setting all the time. So far so good. I can feel the difference when it is on. This is what we needed! Our family suffers from allergies and asthma. After putting the Honeywell HEPA air puffier in the bedrooms and my office, I can really see a difference. My daughter no longer wakes up coughing. Very Happy with the 50250 - 02/23/2016 So far it has cut way down on the dust and pet dander. Spring and its pollen will be the real test, but so far, so good in February. Exceptional value, we have been buying this item for years but now stores have stopped carrying them. Delivery was within the 24 hours of my order. air purifier - 02/17/2016 This product is meeting my needs.

It is louder than I expected. But it gives me a sense that it is really pulling tube air through. I have a parrot that creates lots of dandier. I can definitely tell a difference. 50250...jan 2016 - 01/18/2016 Reviewer: Frank A N I must say the delivery of the 50250 was super fast and received it in excellent condition. After checking a lot of brand in the market,reading reviews. I finally decided to buy this Honeywell hepa a/p. We are using it now for 2 days and we are pleased about its performance. Being diagnosed to suffer from a lot of allergens I can tell it does change the inside atmosphere of our house. I can freely breathe now and sleeping longer hours. I think my English bulldog benefited from this purchase too because she's no longer sneezing as before. Lastly, the noise issue ..the unit is big and making it quiet is a plus factor. Bought this to replace the original series Honeywell HEPA filter...like the change from blowing at the bottom to the top in this model.

After 12 years with the old filter, the new model makes a substantial difference in air quality.purifier air chambre bebe Honeywell 50250 HEPA Air Purifier Manualair purifier humidifier combo singaporeHouse dust mite and pet allergies occur because of a reaction to tiny airborne particles within the home. air purifier halifaxSymptoms can include a runny or blocked nose, itchy, red or watering eyes and wheezing. If you have asthma, your asthma symptoms can also be made worse by these allergies. Regular use of medication can improve symptoms but avoidance of the cause can also be important, especially with pet allergies.Tiny particles found in the air inside the home that cause allergic symptoms are called aero-allergens.

These particles can include the poo (faeces) of house dust mites, and animal saliva, skin and urine. (Mould spores are another type of aero-allergen present in some homes, especially those with damp problems.)Allergens are substances that cause an allergic response in certain sensitive people. They commonly cause problems with nasal, eye (ophthalmic) and breathing (respiratory) symptoms. These include inflammation of the nose (rhinitis), inflammation of the eyes (conjunctivitis) and wheezing. They can aggravate conditions such as asthma.Aero-allergens rarely cause severe allergic reactions such as anaphylaxis. They are, however, some of the most common causes of allergies in general. See separate leaflet called Allergy - General Overview for more details.Treatments do help improve symptoms. Avoidance of these allergens (or at least a reduction in their number) is also important.Allergies to house dust mite and pets are common. Also, in some countries, particularly in the developed world, atopic diseases affect up to 1 in 3 of the population.

(Atopic diseases include asthma, eczema and hay fever.) About 1 in 2 adults with asthma, and about 8 in 10 children with asthma, have an allergic component to their disease.Symptoms of house dust mite and pet allergies include:House dust mites are present in all homes in the UK. They are microscopic insects that live off human skin scales and form part of the dust in our homes. The climate and conditions inside our houses are ideal for their survival. They prefer bedrooms - in particular, beds and bedding. This is:The allergen that triggers the immune system and causes allergic problems is found mainly in the poo (faeces) of the house dust mites. These droppings are very dry, they break up (fragment) easily and the fine particles disperse into the air. The particles settle quickly into our pillows, mattresses, duvets, carpets and upholstery and are difficult to wipe out (eradicate). This means it is difficult to remove the source of the problem and prevent the allergic symptoms.House dust mites are in all homes.

It doesn't matter how clean and tidy you are. They affect homes regardless of lifestyle and income. Improvements in the way homes are insulated, including double glazing, has reduced air circulation and ventilation. As a result, moisture in the air (humidity) in homes has increased. This has made our homes a good environment for house dust mites to thrive.Animal allergens are the second most common cause of allergic reactions. The allergens that trigger the allergic response are found in animal saliva, skin and urine. When animals groom themselves, they lick, and saliva coats the skin, fur or feathers. Skin cells covered in saliva are shed (this is called animal dander) along with loose hairs and fur.Even so-called hairless breeds of cats and dogs can cause problems. Additionally, pets can have flaky skin complaints, like eczema, and so can spread large amounts of dander.These allergen particles are microscopic, and so are easily airborne, and thus easily inhaled. This leads to typical respiratory symptoms, rhinitis and allergic conjunctivitis.

Pet cats are the most problematic animal in terms of allergen production, due to their behaviour of frequent grooming. Dogs come second but any animal can be a cause of an allergic reaction. Parrots and other birds are another cause of allergic reactions to their feathers. In small animals, such as mice, gerbils and guinea pigs, it is the urine that is the most potent allergen. This means that the animal cage and bedding are heavily contaminated with allergen. When the urine dries, and the bedding is disturbed (either by animal movement or by cage cleaning), allergen is released into the air.Many people with pet allergy do not need any tests as the cause of the allergy is clear. Symptoms are worse in the home where the pet is. Symptoms improve when out of the home, especially for longer periods, such as on holiday. Some people with asthma are advised to avoid contact with pets if it makes their symptoms worse, or to try to reduce house dust mite if symptoms are severe or difficult to treat.

If required, both house dust mite and pet allergy can be diagnosed with skin prick tests. This is usually done in a hospital by either an allergy specialist, an immunologist or perhaps a skin specialist (dermatologist).See separate leaflet called Skin Prick Allergy Test for more details.Treatment with nasal sprays, eye drops and/or antihistamine tablets will often ease or clear the symptoms. The treatment is the same as for any cause of allergic rhinitis or allergic conjunctivitis.Treatment with medication often works so well that you may not have much motivation or need to avoid the cause of the allergy. However, some people may wish to try to avoid the cause of the allergy, particularly if medication is not fully effective.If house dust mite is the cause of the allergy, it is impossible to keep your home permanently clear of the mites and their droppings. However, the following will help to reduce their number greatly, which may ease symptoms. The main focus is on the bedroom:Symptoms of house dust mite allergy may also improve when on holiday in warm dry climates where there are fewer mites.

With allergies to domestic pets, the main strategies for minimising allergic problems and aero-allergens are to:This treatment is sometimes used, mainly in cases that are severe and where symptoms are not helped much by other treatments.It is done using a series of injections to desensitise the immune system. The allergen you are allergic to is administered in tiny quantities, via an injection. The amount used is so small that it only very rarely causes the allergic reaction, but is enough to teach the immune system not to react. Increasing doses of allergen are given at regular intervals (usually weeks to months).Immunotherapy is time-consuming and expensive, and it carries a degree of risk. For this reason, it needs to be carefully supervised by a specialist, and performed in a hospital outpatient setting. It would only be tried if other methods had previously failed.A newer technique involves placing the allergen under the tongue (drops or tablets). This type of immunotherapy is increasingly being used in allergy clinics;
